Ds who is 18 months has 5-6 oz of formula before bed. he has cows' milk in porridge every morning and probably eats a bit of cheese or a yogurt most days. he get offered cups of cows' milk daily at home and nursery but won't drink it. i'm not really sure how to approach this. Keeping him on formula indefinitely doesn't seem much of a solution but will he still get enough dairy / calcium if that bottle goes? ideas gratefully received.
