My DD is 21 months old and I have tried to change her from formula to cows milk, but unfortunately she has chosen not to like cows milk (got to love fussy toddlers).
Anyway she eats yoghurt, cheese, custards, vegies and fruit really well and I asked my CHN what I should do about her milk intake. (She was having 240mls of formula in the bottle at breakfast and then again at dinner).
She said to me to take away the morning bottle, but to keep the night bottle until she is 2. Apparently from 2 years of age you can start giving them light, low fat diary etc - as their calcium needs drop after the age of 2.
So each morning I offer her cows milk, and each morning she takes a sip and says yukky and hands it back...
So she now has her yoghurt, cheese and custard and then her 240ml night bottle of formula. At age 2 I will cut out the night bottle and then if she still doesn't want the cows milk, apparently the yoghurt, cheese, custard, fruit and veg etc will hold enough calcium for her to be getting her daily requirements.
I hope this has helped.
