I'm wondering about the transition to whole milk at 12 months. I know that this is because formula is unnecessary past this age as they're getting their nutrition from food, and it's expensive. But I'm just wondering really, would there actually be a problem if you continued with a little bit of formula in the morning and evening instead of cows milk, other than the wasted money? Breastfeeding is recommended by the WHO until 2 years if possible isn't it - so surely formula is closer to breast milk than normal whole milk is?
