Introducing Eggs to Babies
The humble egg has been subjected to quite a wide variety of opinions when it comes to introducing it to your baby. It is also classified as a 'high allergenic food', being one of the top eight food allergens.
Nutritionally, the egg is packed full of important nutrients. It is a complete protein (containing all eight essential amino acids) plus it contains both saturated fat (approximately 1g) as well as unsaturated fat, including your omegas. Eggs have a significant number of vitamins and minerals including selenium, folate, iron, calcium Vitamins A, E, D, B5, B12 and more!
When you look at how much goodness eggs can provide to our babies, it is a food we do want to introduce especially in the sensitive period the first year offers for developing food preferences. However, I know it can be quite daunting when there is such conflicting information and worry considering eggs are a top allergen.
So below I answer some of the top questions and de-bunk the major myths on introducing eggs to babies.
1. When to introduce eggs?
As with all allergenic foods it was previously recommended to be very careful of introducing eggs. When my first son was starting solids, it was recommended to start with an egg yolk at seven months and then egg white around eight months. Inline with new, essential evidence on allergenic foods to indicate that early introduction can reduce the incidence of allergy (Tan et al., 2017) it is now strongly recommended by The Australasian Society of Clinical Immunology and Allergy to introduce eggs very quickly around six-seven months of age. Due to its nutritional power I recommend to introduce egg within the first month. This is highlighted in my week-by-week guide which I have both in my book, The Nourished Baby, as well as a magnetic version for your fridge.
2. What is the best way to introduce eggs?
You do want to try egg on its own for the first time (i.e. not with any other foods) just to see if there is a reaction. You can now give the whole egg together - so no need to do the egg yolk and white separately which will make things a lot easier. In my experience once tried for the first time, scrambled eggs are very easy for babies to have.
3. How much eggs can babies have?
The following is a statement from the Nutrition Foundation:
"It was previously thought that eggs were related to high cholesterol. Studies conducted in healthy people show no effect of daily egg intake on blood cholesterol. In addition the latest scientific evidence shows no association between increased intake of dietary cholesterol and increased risk of heart disease or stroke."
This is a very simple (trusted) summary of current evidence here. In terms of exact amount, there is no 'rule' as such. You still want to get in a good balance of vegetables and other wholefoods across the day, keeping in mind you are developing your babies preferences and variety is important for a broad range of nutrients.

4. Can you give runny egg to a baby?
It is currently not recommended to give a baby raw egg and that best practice is for a well-cooked egg.
5. Is there a risk of Salmonella?
Salmonella is a type of food poisoning caused by the Salmonella bacterium. I have read some blogs, which suggest that babies can contract Salmonella and therefore to avoid introducing eggs in the first year. In New Zealand we have very stringent code of practice in place for the industry for best before dates on eggs and there has not been a single reported case of Salmonella from eggs for over 15 years. Some of the research cited in these blogs is very outdated, does not align with new allergic guidelines (released in mid-2016) and based in the United States. The Allergy New Zealand website is a very trusted source of information on allergic foods, so worth checking out in this regard as well.
6. How common is egg allergy?
Egg allergy is the second most common food allergy in infants and young children after cows' milk allergy (Caubet and Wang, 2011). It usually presents after the first exposure to egg protein.
7. What are signs of a reaction?
An autoimmune response will be evident within two hours, normally very quickly. Reactions can range from a flare in eczema, to hives or swelling around the mouth or more widespread, gastrointestinal reactions with tummy pain and vomiting, to severe reactions (anaphylaxis).
Most children with egg allergy have mild symptoms, but a small percentage of children have severe, life-threatening reactions to even the tiniest amount of egg. Some egg-allergic children can eat well-cooked egg, but not raw or lightly cooked egg. Others are allergic even to egg that has been well cooked (Allergy New Zealand). You might also find this blog on allergic responses helpful.
8. Can children grow out of it?
Yes! In fact the majority of those infants diagnosed will out grow it by the time they reach their late teens. There is evidence to show that slow re-introduction (rather than strict avoidance) especially through baked egg can help to build tolerance (Leonard, 2012). I would recommend doing this with individualised support (this is something I step many parents through in my 1:1 consultations. I do not do a generalised introduction ladder as ultimately all autoimmune systems responses are completely individual and should be treated as such.
9. What about other types of eggs?
If you are allergic to eggs, you will need to avoid eggs from other poultry, such as duck, goose and quail. You also need to avoid both the egg white and the egg yolk. For those not allergic other types of eggs will provide slightly different nutrients, especially vitamins and minerals and therefore are good to try with your babies.
10. What if my baby does not like the texture?
This is quite common, so please do not despair if it does happen. It does not mean your baby will never eat eggs, just that they need a few more opportunities (it can take up to 21 attempts or more) and possibly a different texture to try. Do not be afraid to try a variety of styles from scrambled, to fried (in a healthy oil). You can also check out my Egg and Spinach Cups for a different idea.
In my best selling book, The Nourished Baby, I have a whole section on allergenic foods, how and when to introduce them - including the complete week-by-week plan to help take a lot of the thinking (and worry) out for you! I do a number of events, including virtual events which many parents find helpful and mean you can ask me your questions directly. Just check out my event page
Happy Egg Eating,
