What is the thinking on when it is okay to switch to cow's milk or other drinks? DD1 is breastfed, and feeds a lot at night and in the morning, but has formula on the 3-5 days a week she is in childcare. I am quite keen to carry on breastfeeding, at least through the winter, if not longer. But is 12 months too young to ditch the formula the rest of the time and give her other drinks in a beaker instead? The nursery staff member I spoke to thought not, but thought I should check with a health visitor. She is a great eater, by the way, and has lots of fab food at nursery... but she is there 10 straight hours by the time I drop her off and pick her up...
