Hi
A few weeks ago I had a week of my then 12 week old waking up every 2 hours. That came to an end and I thought great, we’ve survived the sleep regression and she went back to 3 wake ups a night.
Fast forward 3 weeks and she’s back to waking every 2-3 hours for the past 4 nights. Can sleep regression happen in waves or was the first lot just a taster before proper sleep regression kicks in?
