New grandchild & feeling guilty

Its only a few more days. Id stay.
What age is your daughter at home.

Stay

Oh yes and congratulations! 🥳

Definitely stay and make the most of it!

Your DH can get the train back if he misses you that much 😁

Absolutely not!

You’re being a great Grandmother and mother and you’re DH chose to leave.

Congrats on the little one

Hubby us a big boy now .... enjoy lively new baby!

Has your husband always been this clingy and needy? He’s a grown man. Presumably he can survive on his own a few days while you help family.

Guilt-trips are a form of controlling behaviour. Don’t feel guilty about being such a thoughtful mother, mother in law, and granny. It’s temporary and a very normal thing to help when new babies come. You live far, so it’s more than reasonable to spend as much time there as you and son’s family are comfortable with. Congrats! Enjoy your new grandchild.

Definitely stay and help. Those first days are precious, and any help you can give will be deeply appreciated.

Am I being unrealistic to stay?
No.

Is your husband working and does he need the car?
How old is your daughter at home? Is she still a young child? Even so, she must be at school during the day so surely they can manage just for a few days.

Enjoy the toddler and new baby while you can, it may be a while before you see them again.

Yes you are privileged to have been asked. Usually, the paternal grandparents take second place. Are your d.i.l.’s parents not around ?
I think your husband is rather selfish - surely he and your daughter can cope without you. As for your parents, they can look after each other for the moment.
That’s my opinion .

Stay! It’s only another 4 days.

Stay, stay, they are probably big enough and ugly enough to look after themselves fo a bit. It will be a precious time getting to know the baby and helping out. Could your husband not retrieve the car?
