diddl I wouldn't say I was particularly close to my Mum until I had kids. We didn't have a bad relationship, but I have always been closer to my Dad.
It does change when you have kids, IME/IMO. You want to turn to someone who knows what you're going through, who has been there, done that, and can tell you it's all going to be okay in the end...and that person is normally your mum.
My MIL has a daughter but my DD was her first GC. She wanted to take over. I'll never quite forgive her for insisting on coming to meet DD before my parents, on day three when my boobs were on fire and I was trying to get to grips with BF. She barged in to the bedroom whilst I was sat there trying to get DD to feed, boobs out, crying in pain. I didn't want my MIL, I wanted my Mum!
MIL has always said weird things like "you're my daughter now" when I married DH and calls my DD "my little girl" (meaning hers).
There are all kinds of issues in the past she is trying to (over-)compensate for, and it's too much.
And yet she has told me in the past how much she disliked her own MIL...and her own mother in my presence has told her she's being an overbearing MIL to me and to leave me alone!
My MIL means well, I know that, but as another poster said, she is still trying to be the matriarch of the family, which DH and I don't need/want at this stage in our lives.
I do feel sorry for her generation. Their own mothers are only just relinquishing the matriarch roles and just when they think it's their time, along comes our generation of 20/30/40-somethings having kids and wanting to do things our way and not needing their help as much as previous generations would have done. It must be tough.
