I don't exactly remember, but I am sure my daughter drank 2 feedings of milk per day when she was 20 months old. I think that my daughter sort of started drinking 2 feedings of milk when she was 15 months old or so.
神仙魚,
Have you thought of giving whole milk to your son? It tastes better than formula milk. Even my elder daughter is not that fond of milk, she is still drinking 2 feedings of formula milk per day. It's good for your child to drink milk everyday. Does your son eat a lot for lunch and dinner?
二十個月大的bb可以飲鮮奶既呢咩? Yes. Give him a small glass to try first. If he is not allergic to that, give him half a cup for brunch or afternoon tea.
It's good that your son 早餐大約飲七安,晚餐大約飲八安. No worry no worry. Cheese is also good enough. My doctor told me to relax on the milk consumption of my kids. He said cheese, fresh milk, yogurt are as good as milk. As long as your son has balance of diet, he should be fine.
