I'm in exactly the same boat. My baby rarely even contact naps anymore and gets so ratty by the afternoon. I've even tried lying with her in a pitch dark room and it doesn't work. It is very frustrating. I've taken to putting her in the car and driving around. But that only works occasionally. And 9/10 she's awake as soon as the engine is turned off.
@Lindsey yes he won’t even sleep on me! This is baby number 2 so I’m also very split during the day I try the dark room when my daughter is at nursery and that hardly ever works but during the day when it’s just me I’ve got 0 chance of being able to spend massive amounts of time in a quite dark room I’m honestly at a loss 😩
I posted about this earlier for advice for me. Its a bit further down in this group but might be useful for you! What helped me today is go up to a dark bedroom at the very first yawn, give dummy and put him on his side while i cuddle him or rub his back. Still only 30-45 minute naps but when i napped with him for one he slept for an hour. Not ideal as i really want him to be able to go to sleep himself but for the last few days he has been screaming before each nap and this is the only thing that helped for now.
