16 weeks old and wakes up 3x a night for feeds (is bf). She goes straight back to sleep after each one, but it's just exhausting still being up so often. During the day I offer her a feed about every 3 hours but she barely takes anything, and her nappies aren't as wet as I'd expect. She is healthy and happy and growing so for her it's not a problem but for me it is! I have a 2yo to run after too! Any advice?
