I loved having my oldest sleep with us (that was because she would snuggle me and kick her mom out of bed ). But, that did not last. My little girl some times joins us but not very often. Being she is a girl she is VERY hot blooded. She thinks daddy is an infernal so she does not like snuggling as much. My guess is your little girl will follow suit at some point. And if this helps daddy and the little misses (who it sounds like already has her daddy wrapped around her finger) bond I say good. Since it sounds like this is not constant, I (being a guy though) would not worry too much. Besides, sounds like your DH is trying to help you out as well, something some guys dont do. He is letting you get some rest that you need and bonding with his little girl. Just take alot of pictures!
