it's normal. maybe during the day try to give more water or fresh milk, and at night try buat susu formula lebih dalam sebotol tu. like my son dia minum 2 bottles during the day, and dia ni jenis kerap haus so I selalu bagi air masak or fresh milk and makan lebih. then malam tu i buat dalam 8-10 ounces of formula milk, alhamdulilah dia tidur lena till pagi sebab kenyang
itu normal sis..
