Nup, made no difference here. Jazz just gets up early... mostly with the sun, I guess it's who she is. She is sleeping later, the other day it was until 6.30am WOOHOO! We had a great sleep-in!

Also, if he's sleeping a decent amount at night then I don't see why he would NEED to sleep longer, KWIM. 10 hours is decent, does he really NEED to sleep longer? I know he seems tired in the morning but I don't think has much to do with how much sleep he needs at night, more to do with how much time he is able to be awake for.
