Hi, having a really hard time with 4 month sleep regression at the moment. Some nights are great, for example Wednesday night he slept 6 hours straight, Thursday we had two 2.5 hour stretches but then last night (a more typical night) I was lucky if he slept for 1 hour. I don't understand why he can link sleep cycles and self sooth some nights but not other nights.
I'm trying to really concentrate on getting his daytime sleep right in the hopes that it will help make the nights easier. He wakes up at a different time every morning and it's a struggle to get him down at night so impossible to set a routine. I try to make naps as long as possible but he is normally awake after 30-45 minutes.
I've attached a screenshot from my BabyTracker App showing every sleep he has had since he went down at 23:30 last night (so you can see how awful the nights are). The text showing times in between where sleeps are recorded are the awake windows.
Thank you kindly for any advice!
TLDR: Photo attached from tracking app showing babies sleep. Please help me see where I'm going wrong!
