My younger sister is fed-up because her DS2 seems hungrier and wants more bottles now at 4m. Some of her FB friends have said to start him on solids, they were advised to wean at 3.5m, 4m etc. I very gently let her know about the research advising 6m, and her own HV has advised 6m. One friend is saying that just because milk has more calories that won't necessarily fill him up more than baby rice or purees, and that obesity can stem from over-feeding milk (he is ff). Sounds like bs to me, but I'm no expert either.
I bf and no nothing about ff. I don't want to go on at her, but don't want her to take bad advice at face value either.
