Hi, my little boy has a dairy allergy too, it's surprising howu much of it there is around. It's early days with weaning for us and he is still mainly interested in milk. I switched to oat milk rather than soy as someone had mentioned the chances of soy allergy were higher. I chatted to a health visitor about it recently. She recommended pulses, humous, fish, chicken and not worrying. But did say I should ask my health visitor for a referral to a dietician, haven't done that yet but will do soon.
