Our 4 month old DC is waking up 4-5 a night. I am the one that gets up. This week DC woke ON THE HOUR during the night. 
I take over on the whole because DH works.
I also work...
DH commiserated my getting upbhourly with the fact me getting up gave him a disturbed night... but offered to be on night duty last night so I could sleep. So at 3.50 I dealt with child as he wasn't up. At 5.50 he rolled over and said " your turn".
AIBU to throw a saucepan at him?
