I changed the #2 milk at 7 months but failed because Ah B poo poo very 希 with 泡泡. Then I changed back to #1 again. When Ah B 11 months, I tried to changed #2 upto now. (Ah B is now 12.5 months)
My daugher is also taking A+, she will become 1 years old next week but I still let her drink No.1. I think I will let her change to No.2 after taking the 1 year old injection.
