Hi everyone, new member here. I have a 16 week old baby and she has always slept very well. She is now going 8-9 hours over night and I quickly got very used to having decent sleep again! I'm dreading the impending 4 month sleep regression and I just wondered if it is really awful? Do all babies experience it? Did anyone get away with not much disruption to their baby's usual sleep routine? I'd be very grateful for anybody's experiences, brilliant or horrendous! Thank you x
