I know this has been posted before in years past but I just had Baby #2 so that's why I am posting a new similar post.
I can't stand how my MIL is obsessed with my DD (22 months) because she never had a girl. When she is visiting she chases my DD down for a hug or kiss and not in a playful way, she'll just pick her up while she's playing and say she has to give her a hug and kiss!
DS is a week today and again her only idea of helping is holding him. And that's only when she was here. She hasn't offered to help in any way since he was born. I've even asked for help juggling the two of them while my DH goes to work one day over his two weeks off but she was too busy/couldn't come over.
I'm anxious to tell her it's not happening again. I'm putting my foot down more this time. To those that may not understand, I don't want her holding/hogging my babies because they are my children, she has her babies, my DH and his brother aged 37 who still lives at home. Plus my DH and I went through a lot of trouble to have our children. We didn't have them for her.
Re: MIL hogs/obsessed with babies
As far as her not offering to help, that does suck. I'd say be as direct as possible in whatever help you need/want from her. If she refuses or makes excuses, there's not much you can do. You can't force someone to help you. It would be pretty spiteful to decide that because she won't help in the way you want, she can't hold her grandchildren (not saying that's your reasoning btw, just throwing that out there just in case.)
