It's a tiredness one! Inspired by the dressing gown of doom thread and the ongoing bickering between me and 'D'H.
7 month old doesn't sleep through the night. They don't. It's what babies do, I accept this.
I sleep with the baby. She is up for a feed between 2 and 4 times a night. Often co sleeps while starfishing and edging me out of bed. Once a week maybe is so resistant to being settled I call DH to help.
DH sleeps in the spare room. Usually through the night. He gets up with the 3 year old who is up without fail between six and six thirty. I'll generally give him the baby at six thirty and sleep for a hour or two.
We are both thoroughly knackered and the constant bickering about who has more right to be tired is driving me crazy (its me, yes?!)
