You poor thing, i go through exactly the same with DP... EVERY night i get up and have since DD was born.
He works 6 days a week and gets HIS sleep in on Sunday, i fell asleep on the couch the other night, he woke me up to tell me DD was screaming at about 11pm.
I went in and he had taken her to bed with him and said, she has been like this for 40min.. I TRIED.. it was like he wanted me to give him a medal for not waking me up... i said do this at 3am for 2hrs straight then come tell me you have done a great job!
He doesn't THANK me for letting him sleep.. it's a GIVEN!

I hope you get a nice big sleep in one of these days, anything past 6 here is a sleep in aswell.

GL and big
