My daughter is 3 months old tomorrow and she's now drinking 7oz bottles and sometimes only going 2 hours between feeds and sometimes cries when she's finished a feed. We only went up to 7oz last week as she was clearing 6oz. It probably takes her about 10-15 minutes to clear a bottle she's on cow and gate milk. I'm starting to worry that it's not filling her up enough. Is this normal? She normally has 6 feeds a day but sometimes this isn't enough and it's more like 7. She sleeps through the night she has been doing this since she was 9 weeks old and she's very advanced for her age not sure if that has anything to do with it x
