Went to clinic today to discuss how weaning going and HV said that I should get some vitamin drops for DS. She said that all breastfed babies need them from this age on (but formula fed don't as already in milk, which I guess makes sense). Is this REALLY the case if I can get him to eat a varied diet, even at the start of weaning? I guess using them can't hurt, but wondering if what she said about breastfed babies really true.
