My 8 week old has been a pretty good sleeper up to 6 and a half weeks. He will now sleep around 8-12/1 but then wake every 30 minutes- an hour. I know fussiness can increase at this age and taper off towards 12 weeks. It also isn’t because he is needing to feed as he will have two feeds during the night but apart from this doesn’t really drink much when I offer him a feed. Does anyone have experience of this and how long did it last for you?
