This is what I noticed with my little girl, at the age of 1 she starts to drink less milk as already is eating solid foods like vegetables, cooked meats, noodles, and some finger foods which does keep her full most of the day. I did worry for a bit, but when I started to switch her milk to a toddler’s milk, it does have a label at the back that says after 12 months it is recommended that a child drinks around 500ml of milk per day. So usually that would be around 2 to 3 servings of milk in a day. If you are still worried, cheese can also be a good alternative. Hope this helps.
