The idea of giving your baby foods like egg or peanut for the first time can feel nerve-wracking. Many parents grew up hearing that these foods should be delayed, but current paediatric thinking has shifted. Introducing common allergens early and regularly, once your baby is ready for solids, is now generally encouraged and may help lower the chance of a food allergy developing. This guide offers warm, practical general information to help you feel prepared. It is not medical advice and is not for self-diagnosis, so please speak to your doctor about your own baby, especially if there are extra risk factors.
When and How to Start
Most babies are ready to begin solids at around six months, once they can sit with support, hold their head steady, and show real interest in food. Common allergen foods can be part of this journey rather than something to save for later. The usual advice is to introduce them one at a time, in a form that is safe for your baby’s age, and to keep offering them regularly once tolerated. If your baby is already eating a first food happily, our guide to introducing solids and weaning in Singapore sets out the wider basics.
A calm, unhurried approach works best. Consider these gentle steps:
- Offer a new allergen food earlier in the day rather than at bedtime, so you can watch your baby afterwards.
- Start with a small amount, and if all is well, gradually offer a little more.
- Introduce one new allergen at a time, waiting a couple of days before trying another, so you can tell what agreed with your baby and what did not.
- Once a food is tolerated, keep including it in the diet from time to time rather than stopping.
The common allergen foods to include over the early weeks and months of solids typically cover egg, peanut in a smooth baby-safe form, dairy, wheat, soy, fish, shellfish, tree nuts, and sesame. Always serve them in a texture that will not cause choking, such as smooth pastes thinned into other food, and never whole nuts or hard lumps. Checking your baby’s hunger and tired cues helps you pick a moment when they are relaxed and ready to try something new.
Speak to Your Doctor First If There Is Higher Risk
Some babies deserve extra care before allergens are introduced. Please speak to your doctor or paediatrician first if your baby has:
- A strong family history of allergy, such as a parent or sibling with a diagnosed food allergy.
- Existing eczema, particularly if it is moderate or severe.
- Any known reaction to a food already.
In these situations, your doctor can advise on the safest way and place to introduce certain foods, and whether any checks are needed beforehand. This is guidance to follow with a professional, not something to work out alone. If eczema is part of the picture, our notes on baby skincare and eczema in Singapore may be a helpful companion read, and having a regular doctor makes these conversations easier, so see choosing a paediatrician in Singapore.
Know the Signs of a Reaction
Most babies try new foods with no trouble at all, but it helps to know what a reaction can look like so you can respond calmly and quickly. Milder signs may include:
- Redness, hives, or a raised rash, often around the mouth or on the skin.
- Swelling of the lips or face.
- Vomiting, tummy upset, or sudden fussiness after a food.
More serious signs need emergency help without delay. Call 995 straight away if your baby has any difficulty breathing, noisy or wheezy breathing, swelling of the face, tongue, or throat, sudden floppiness, or seems very unwell after a food. These signs can point to a severe allergic reaction, and speed matters. Do not wait to see if things settle, and do not give any medicine on your own or guess at doses, as emergency care is the right response.
If your baby has a mild reaction that then passes, note down what the food was and speak to your doctor before offering it again. Keeping a simple food diary during this stage makes these conversations much clearer.
Keeping It Positive
Introducing allergens is a normal, hopeful part of feeding your baby, not a test to dread. Go gently, one food at a time, stay nearby to watch, and lean on your doctor when there are extra risk factors. In Singapore’s warm weather, offer new foods when your baby is comfortable and not overtired, and keep mealtimes light and happy. With a little planning and the confidence to act if needed, you are giving your baby a strong and varied start.
