cows milk

hi mums! my son is 10 months old and so we’ve recently had our health visitor review (we live in UK) she was talking about cows milk and how he can have it in foods as an ingredient (which we have been doing anyway) but not to drink on its own just yet. i’ve been looking into the whole ‘cows milk as a drink’ thing and have seen differing things. some waited until baby turned 1 and others ‘weaned’ their baby onto it from 11 months. just wandering what you guys have done with your LOs? i didn’t think much of it to begin with but the research just has me curious aha xxx
