Same problem as my baby(18 months), if your BB
really don't want, try to feed with others milk products
like Cheese, ...! You can also consult nurse in government
BB health centre.
My practical experience is my son changed to No.2 milk while he was 7.5 months old. However, though his "ng ng" is okay by that time. He refused the milk and even he saw the bottle of milk, he will run.
Then I tried to change the brand for him and at the very beginning of the day, he changed a little bit and drink more. Up till now, he likes the milk very much, he must drink a bottle of 200 oz upon wake up in the morning. Sometimes, I prefer to give him bread but he still wants the milk first before taking the bread.
