K.I.
Mine wasn't all that helpful honestly. He was great with giving them baths (well really just taking them in the shower with him) and diaper changing...but he wasn't big on waking up in the middle of the night or holding them just because...he didn't mind getting them dressed, as long as I picked out and set out all the clothes...
But as soon as they were more mobile-it was on! He is a wonderful father and very involved...it was just really hard for him when they were newborns, so small and fragile and he really felt as if he wasn't needed by them (No Boobs! :)
I did my best to let him know that I needed him and that yes, the itty bitty babies needed him too!
