DS is 15 mnths old.He has been mostly breast fed with 1 feed aday of formula since 3 weeks old.He now eats 3 good meals a day.He is b/fed in the morning and just before bed and he has a bottle of cows milk before his afternoon nap and a beaker of cow's milk for elevenses. I am thinking of giving up the evening feed as it takes forever as he spends more time bouncing on the bed etc than feeding. Should I replace this with a bottle of cow's milk or does he not really need a drink before bed . I don't want him to not have a drink if he needs one .
