@Mish He is coming up to 16 weeks on friday. Cows milk protein? Is there a milk without this?
Yes, some babies can find it hard to digest (there’s a whole group on here for CMPA). If you are in the UK, yes there are soya based powders but I believe you need to get them on prescription. I think you really need help from a health professional. What symptoms does your baby have?
How old is your baby? It Is really unusual for an under 2 to be allergic to Lactose, as it’s something that is normally developed in later life. Cows milk protein allergy however, is quite common, but lactose free milk won’t help if that is the issue
