some really unkind comments here (as usual).
Fair point, but I think the comments are fair too.
He has since said it would only be to sleep- as in come here about 9pm then he’d by up at 5am the next morning for work.
When has he stated that his girlfriend will be able to get 5 nights of uninterrupted sleep per week? Or any nights of sleep for that matter? Or is this just about him?
He’s an excellent Dad - very hands on and extremely supportive of his gf.
Except during the nights.
They are currently staying with her sister who is also very helpful with the baby during the day.
That's great, but it shouldn't be used as reasoning for him stepping down from his responsbility as parent. His girlfriend's sister is not a parent to the child, your son and his girlfriend are.
I have told him no, he cannot stay here. I have however offered to have the baby overnight as I am very concerned that he’s not coping with the stress and sleep deprivation.
I can't see the new mother wanting to hand over her young baby to her PILs overnight just because Dad wants a good nights sleep. Have they not got a sofa he can sleep on so he doesn't have to be disturbed by the mother doing nightfeeds? That way he is still there to help if the mother needs him.
I think that’s a good compromise.
