How to wean a baby with cow’s milk allergy

Understanding weaning with cow’s milk allergy (CMA)

Weaning (complementary feeding) is when your baby begins to transition from being fully milk-fed to getting some of their nutrition from solid foods. This should be an exciting stage, but for many families, it can feel uncertain and even overwhelming.

If your baby has Cow's Milk Allergy (CMA), weaning may feel particularly daunting. You might have lots of questions about when and how to start, which foods you can give, how to make sure your baby is getting enough calcium, and what to do about introducing other allergens like peanut or egg.  

In this weaning guide you will find everything you need to know about when to wean, which foods to give and lots more. Weaning isn’t ‘one size fits every baby,’ and this information will help you plan what works for your baby.

When to wean – how to spot the signs your baby is ready to wean

The first question you may have is when to start weaning.

Focus on your baby’s signs of readiness rather than on the calendar. Many babies will be developmentally ready at around 6 months, but others will be ready a little before this and some a little after.1 So the first thing to do is to get familiar with the signs to look out for which will show it is safe to start. 

4 signs your baby is ready to wean2

    1. They are able to hold their head up without support, with no flopping or slumping
    2. They are able to sit with little or no support, managing to maintain a seated position on their playmat or in a highchair.
    3. They have good hand-to-mouth coordination and can intentionally pick things up (usually their toys!) and deliberately bring them to their mouth.
    4. They can swallow solids - when you start with solids, if your baby pushes food out, they may still have the tongue-thrust reflex. Pause and try again in a few days.

    ‘The tongue-thrust reflex is an involuntary response that young babies have to solids being placed in their mouths - it is a clever mechanism which helps prevent choking)

    It is important to remember that all babies are unique. If there are any developmental concerns, if your baby was born prematurely or has severe reflux, always seek expert support.

    Babies with existing allergies such as CMA, or those at high risk of food allergy, may benefit from careful early introduction of allergens to help protect them from developing further allergies. Your healthcare team may recommend before your baby is showing all the signs of readiness to start weaning. Your Paediatrician, Dietitian or Allergy Team can support you with what is right for your baby.

    Spoon fed or baby-led weaning? 

    The next question will most likely be how to approach weaning. In recent years, baby-led weaning (BLW) has become a popular alternative option to more traditional spoon feeding. This can put pressure on parents to choose which of these approaches to use.

    Current evidence shows there is no single ‘best’ approach. For many families a combination of BLW and spoon feeding works nicely. Some babies may have a strong preference for finger foods from the very start, whilst others will do better with being spoon-fed, having finger foods introduced a little later.3,4

    StageSpoon-feeding ideas for babies with CMAFinger food ideas for babies with CMA
    Around 6 months

    Pureed or mashed bitter vegetables, such as cauliflower, broccoli, courgette, spinach or green beans - these foods help introduce bitter tastes early.

    Pureed or mashed starchy vegetables, such as sweet potato, yam or plantain - these will provide energy.

    Fortified oat porridge made with expressed breastmilk (human milk), your baby’s hypoallergenic formula or a fortified plant-based milk - for lots of iron and calcium as well as other nutrients.

    Fortified plant-based yogurt, such as soya or oat-based options - choose products with added calcium and iodine.

    Whole florets of soft steamed broccoli or cauliflower

    Long slices of soft steamed courgette

    Long fingers of soft steamed sweet potato

    You can roll these finger foods in fortified porridge oats, or finely ground nuts such as almonds, to help make them easier for your baby to grip.

    7-9 months

    Look at building in a wider range of vegetable tastes, whilst still including bitter options regularly. Carrot, pepper, tomato, beetroot and pumpkin are all good options.

    If your baby is ready for chunkier textures, try fork-mashing vegetables and fruits rather than pureeing them. Add a little expressed breastmilk (human milk), or  hypoallergenic formula, to help loosen the consistency.

    Add cooked couscous or pasta stars to mashed vegetables, or try mashing small portions of family meals - just take care not to add salt in cooking.

    Try to include a fat source with your baby’s meals to help meet their high energy needs - good options include adding a drizzle of olive oil, some mashed avocado or dairy-free cream cheese.

    At this stage you should try to add in some more protein sources such as soft, cooked red lentils, mashed chickpeas or cannellini beans, crumbled tofu or soft flaked fish.

    Start planning the introduction of peanut and egg if you are going to include these in your baby’s diet.

    Large unsalted rice cakes or corn cakes - try spreading these with some mashed avocado, mashed banana or peanut butter

    Homemade pancakes, made with expressed breastmilk (human milk), your baby’s hypoallergenic formula or a fortified plant-based milk

    Strips of toasted wholegrain bread, spread with smooth peanut, almond or cashew nut butter

    Strips of omelette

    Large pieces of fruit and vegetable which your baby can hold with both hands and easily control

    9-12 months

    At this stage, aim to offer family meals, ensuring textures are safe for them. A few examples include:

    Homemade lentil or meat bolognese with well-cooked pasta

    Cauliflower cheese made with hypoallergenic formula or fortified plant-based milk and dairy-free cheese

    Curries with pulses or meat, mashed as needed to remove any choking hazards (such as whole chickpeas)

    Try to introduce a range of finger foods which will help your baby practice their pincer grasp - squashed chickpeas, black beans and blueberries are good options (ALWAYS squash these, to help minimise choking risk.

    Pastry pinwheels made with dairy-free pesto

    Finger sandwiches with hummus, mashed egg or nut butter fillings

    Fingers or torn pieces of tofu, seasoned with herbs and spices

    12 months+

    By this stage your baby may be making good efforts to spoon-feed themselves, or they might still need lots of support.

    Continue to offer family meals, taking care that the texture is adjusted suitably to your little one’s abilities, and that you avoid adding salt during cooking.

    Your baby may have developed a strong preference for self-feeding. Giving them a range of foods which are nourishing, and can be eaten by hand, will help them develop more independence. 

    note these are on the list of the top 14 food allergens

    “If you are worried that your baby is having an allergic reaction to any food you give them during weaning, seek medical help immediately. Afterwards, your Dietitian will be able to support you with the appropriate next steps.”

    Fortified plant-based drinks can make a really valuable contribution to your baby’s weaning diet. However, they are not appropriate as a main drink until after 1 year of age. Your Dietitian will give you more guidance on this and advise on suitable options.

    Weaning with CMA - winning tips

    • Eat together as often as possible – babies learn by watching you, and this will help encourage them to try more new foods
    • Keep mealtimes relaxed and positive - this is so important to support weaning progress
    • Choose naturally dairy-free foods - this can help save time, money and mental energy when shopping. Good options include fruits, vegetables, potatoes, oats and eggs.5
    • Try to focus on foods which are a normal part of your family’s diet when choosing what to introduce to your baby
    • Don’t be afraid of flavour! Many babies love stronger tastes - try adding a squeeze of lemon juice, sprinkle of cinnamon or some fresh herbs to their meals, to keep things interesting
    • Include iron-rich foods with every meal (e.g. lentils, beans, eggs, meat or fortified cereals, all served in an appropriate texture). Iron is essential for healthy red blood cells, oxygen transport and immunity. Babies born at term will have built up an iron store to last them until around 6 months but from then, stores begin to reduce.6
    • Think about Calcium – Calcium supports healthy bone development. When your baby has CMA, you need to be extra careful that they are eating enough. Some foods rich in calcium include fortified plant-based milks and yogurts, fortified oat cereals, tahini, and calcium-set tofu. Drinks of breastmilk (human milk) or your baby’s hypoallergenic formula will also provide lots of calcium.7
    • Go at your baby’s pace and try not to compare them to others - all babies progress differently and as long as you are progressing, you’re doing a great job
    • Don’t struggle alone - if weaning your baby with CMA feels difficult or overwhelming, seek support. The right expert help will allow you and your baby to have a positive weaning journey which you can both enjoy.

    The role of hypoallergenic formulas during weaning

    For breastfed/chestfed, formula fed and combination fed babies, their milk will continue to be an important source of nutrition throughout their weaning journey. It should continue to be given as their main milk drink until at least 1 year of age and can also be used within weaning foods. Expressed breastmilk (human milk), or hypoallergenic formula, can be used to make porridge, pancakes and white sauces as well as to adjust the consistency of pureed or mashed foods. 

    When to seek professional help

    Seeking expert help will allow you and your baby to enjoy the weaning journey with confidence and calm. You may need some extra help if …

    • Your baby isn’t growing well
    • Your baby doesn’t seem to be progressing with food
    • Mealtimes often feel stressful for your family
    • You are spending lots of time worrying about your baby’s eating
    • Your baby is struggling with certain textures of food
    • You feel unsure about managing their CMA and if/when to start the Milk Ladder

    Frequently asked questions

    What are good calcium sources for my dairy-free baby?

    Fortified plant-based milks and yogurts, calcium-set tofu, fortified cereals and tahini are all good sources which can be included in the weaning diet.

    My baby is refusing all solids; what should I do?

    Stay calm, keep meals relaxed and try to remove any pressure. Try offering food in a different way, for example by trying more finger foods, as your baby may prefer this.

    How do I handle cross-contamination at home or when eating out?

    Label foods clearly and ensure all caregivers know what is safe and how to manage reactions.

    Try to have a range of meals and recipes which are dairy-free, and which the whole family can enjoy - this will help cut down on cooking time. 

    Do I need to avoid other allergens if my baby has CMA?

    Not necessarily. Many babies with CMA will be able to tolerate other food allergens without any problem, though this depends on your baby’s individual risk factors. Speak to your Allergy Team or a Dietitian for expert support.

    Do we have to introduce every new food individually for 3 days?

    Food allergens should be introduced separately, but for other foods, it is fine to introduce new options together, for example in mixed vegetable or fruit purees.8

    How can we safely introduce other allergens to our baby’s diet?

    This is individual to each baby and will depend on their existing allergies, eczema, and previous allergic symptoms. Seek expert support with introducing other allergens to your baby’s diet and remember that delaying this can increase the risk of them developing further allergies.

    Do I have to avoid giving my baby salt?

    Avoid adding salt or giving salty processed foods to your baby. Small amounts in foods like bread, dairy-free cheese, baked beans and cereals are fine, just be mindful of the overall amounts they are having.9

    Which baby pouches should we use? 

    In general, it is best that your baby’s weaning diet focuses on homemade meals and family foods. Using pre-prepared baby foods regularly may slow your baby’s weaning progress and limit their nutritional intake. If you do opt to use some pouches for convenience, check the nutrition labels to ensure the products you choose are dairy-free.
