we recently moved to london from the states, and since our move, our 2.5 year old has had a harder time sleeping alone at night. he wakes up at least once a night crying, wanting us to tuck him in again... he also tells me that he is scared of other kids and random things like a smoke detector outside of his room! i'm concerned because we are hoping to have him start nursery in september, and he will be there 4 times a week. any tips on helping him adjust? this would be the first time away from me... yikes.
