Thanks a lot! Andrew is around 16-17lbs now though he is still not good at drinking milk. He drinks about 3-4oz everytime in 3 to 4 hours, making less than 30oz each day. He is now taking Enfamil together with a little breast milk, just wonder if he needs to change to another brand of formula. As I still didn't bring him to "health centre", I didn't get the advice from the nurse/doctor up till now.
The weight of Trevor tells that he is growing very well. He must be very strong by being a full breastfeed baby!
