There’s an 8-10 months one so he could just have it early which my little one did too, but also teething can keep them up and make them fussy through the night mines the worst for it🥲but it does pass the broken sleep is the worst but will get easier
I have this with my daughter and I was told that apparently when they’re learning a new skill they tend to wake up more to practice that skill - for example rolling over.. I’m hoping it doesn’t last long 😅
So a regression can happen at anytime where there is a developmental leap-so baby learning a new skill…sitting, crawling, rolling etc etc and of course sleep disturbances can be down to teething and pain too-all babies handle this differently. Can you give him some pain relief to see if that helps. I am confident that if his sleep was solid it will most definitely come back. Offer comfort if cause when needed but also stay consistent with his routine! I know it’s hard Mama but it will pass x
