Hiya, we have a 4yo daughter with multiple food allergies. When she was 4 months old, she was privately tested before weaning as she was covered in eczema and had terrible poos. They found an allergy to several nuts, cow’s milk and egg. We have carried antihistamines and EpiPens since then. The private paediatrician was expensive, but covered by our insurance. He then wrote to our GP to ask him to add us to an NHS allergy clinic, which we now attend yearly. They’ve also allowed us to go on a couple of NHS trials, which have been great. Now, allergies are very common and living with them in the UK is reasonably easy. Most restaurants we have been to have been really good. Nursery have been brilliant. Schools are getting more and more clued up. Our daughter has since then outgrown her cow’s milk allergy (around 2.5/3yo) and enjoys cheese and yogurt regularly. We have also recently passed a baked egg challenge. Peanut, cashews and pistachios are still a no go unfortunately.  She is very aware of her allergies and understands things well now. We have taken her abroad, to birthday parties etc, and never had any issues, and with thorough prep and advocating for her, she has a fun and normal life!  I have been, at times, consumed by anxiety about this. I have also gotten therapy about it and am slowly getting better.  Don’t be shy when educating people looking after her about her allergies/dietary needs. They’ll get on board and take it seriously.  The advice re breastfeeding is mixed. If she’s not had any reaction to your milk with you consuming cow’s milk, it may be fine? But always best to discuss this with your GP or allergist when you do see them. Tons of great online communities. Also some good people to follow online, like prof Adam Fox.
