Ok. Am just going to give you what I get advised, don't flame my fat arse, ok? I muttered, with both dds about switching to cows milk at 12 mo. Paed bolloxed my arse with dd1 said ok, if you must, be v gradual. Never got there.
DD2, suggested the same at nursery. Big
faces and I switched her to a half and half follow on milk that you people don't have or don't believe in. She's fine.
Dairy is a huge step from either ff or bf. most kids will cope. Some don't. Dairy milk is packed full of proteins that some LOs can't handle yet. Follow on milk cuts them out.
There is a scientific reason that us continental parents give our kids follow on milk until 15-20months. It's partly lab influence but my paed says ( and this is a paed who NEVER gives drugs unless necessary, right up to ordering bizarre potions to avoid pharma based prescriptions) to go from first ff to cows milk very gradually.
So, those of you having trouble going from ff to dairy, maybe look at the follow on for your brand? I know nhs is against it, but maybe try?
