Re: Co-sleeping is not working so well anymore :(
I'd say it's normal, he feels safe is right.
My DS is still a night time cuddler-- but my daughter prefers her spaces so we've set the crib up as a side car sort of deal-- there was another mom who had a good picture of how it works. She'll nap with me and cuddle-- but at night she wants her space.
Or she wants her daddy. Which si funny.... the man who in the beginning (with DS) said there would be no cosleeping.... is the biggest advocate of it now. He'll sleep on the other bed with her sometimes. It's so cute because she just snuggles into him.
