Yes! We are going through this, too. It's been since Christmas. Started with being scared of shadows/ nightmares to now just waking out of habit and asking for anything or so he can get out of bed X
We've had this and I think it may have been growing pains, as she's recently shot up
My little boy was exactly the same when I was pregnant with my youngest and getting close to his due date! I put it down to sensing the change, he was waking in the night, overly sensitive/emotional and very clingy. This went on for a while and he didn't properly settle back down again until I was around 4-6 weeks postpartum😫x
