My 15 week/3 and a half month baby (my first child) has completely stopped peeing in the night, it stopped a couple weeks ago or so. She feeds loads during the day, rarely much longer than an hour between feeds, anywhere from 2 to 5 times a night (we safely cosleep) and has wet nappies during day but less now than she did. She is healthy and has put on over 3 kilos since birth, developing normally and happy in herself.
Is this normal?
