Definitely sounds like separation anxiety. It's a big change for them going to nursery especially as this is a prime time for separation anxiety to start. My little girl doesn't go to nursery yet but the past 3 nights she has cried when going to bed and calling for me and her dad. Tonight I laid her into her cot said "lay down now, it's bedtime, mummy is still here" then I stayed stood in her room for about 3 mins. She settled and went to sleep. They just need some reassurance x
You just have to ride it out babes. My daughter was the same when she started nursery last year in September. She was literally in our bed pretty much every night for at least three months and I almost lost hope of her getting back into her own bed. But now that she has settled in nursery, her sleep pattern is back to normal and she is sleeping back in her room and we now have the bed to ourselves again. It is a phase and it will pass. It's just separation anxiety at the moment. He will hopefully get used to being looked after by other people and feel comfortable to be without you. It's daunting for them to go from being looked after you to being looked after by a total stranger. We really don't give them much credit x
I think you probably need to ride it out. It's the separation I would guess. Bedtime and naps are another goodbye and if he's started nursery he's just probably really missing you /dealing with a big adjustment getting used to other caregivers. Hopefully it'll pass quickly but fully appreciate a very wiggly toddler in bed is not anyone's idea of a good night sleep! 😴😴
