Grandparents

i can see from your mums pov - she spends a lot of her time with kids, planning lessons, teaching etc. she probably looks forward to her holidays to see her friends and use the opportunity to unwind.

i am always the one who reaches out to my partners mum and goes over - because she works a lot. but whenever we go over she will dote on our son, she has clothes and toys that she bought for him.

have you spoken to her and told her how you feel? you should talk to her and let her know your POV and that you want to feel like she wants to see her grandkids.

Are your kids at nursery?

Honestly. I understand both sides. In the nicest way possible. You are her baby and all grown up with your own baby. She wants to be able to enjoy the freedom of life whilst she can as life flies so quickly.
I thought my mother would be there for my LO always but apart from a handful of times and video chat thats all we see of her.

Honestly yes. Is she not allowed to see her friends and make plans with them? Maybe she can only see them during the week on holidays too, and it sounds like she’s very involved otherwise if you see/speak to her often, and you’re seeing her at the weekend?
What did you want/expect her to do?

If you visit often, she speaks with them often, I’d say you are already in a much better situation than most. Like others have said, she has her own life and people she wants to see whilst she has the time off, which can be very difficult to do with friends when your schedules don’t align and you are stuck with a ridged job.

My wife and I both teach and this week she’s spent everyday with friends or getting out and about when normally it’s very difficult with the long hours and I have come back home with our daughter to see her mamma and auntie so she can enjoy the time without worrying about us being at home.
