I'm actually having some diplomatic issues of my own this year, and could use some analysis of the situation.
My parents are very close to DS. They've recently moved to be closer to us, and see DS about twice a month. They've baby proofed their house, and have gone out of their way and to considerable expense to create a safe co-sleeping arrangement for us. He's really comfortable with them, and I feel very comfortable leaving them with him when we go out.
MIL and FIL haven't gotten to spend as much time with DS. Their finances are tighter and they're less able to travel because of numerous health problems. They also live twice as far away as my folks, and can't really put us up very easily when we visit them. I don't always get along with my ILs, but they're good people, and they love our boy.
We've recently been made aware (by FIL) that MIL is very very sad that she doesn't know our son better, and is jealous of the relationship my mom has with him (and I suspect thinks that I'm to blame for that).
They're all coming to our house for Thanksgiving. My folks are leaving Friday so his folks can have Saturday with him to themselves. Any ideas on what I can do to encourage a 21 month old to become more attached to his paternal grandmother, who can't get on the floor, can't pick him up and hold him, and likely is going to continue to not see her as often as my mom?
Re: Speaking of holidays and IL's.... I need advice
I know that reading books doesn't take too much energy. Maybe she can read to him while he is sitting on your lap until he is more comfortable with her then transition to her lap (if she is healthy enough to hold him). She could also sing to him with actions.
I know it will be cold but I used to play with blowing bubbles with my toddler niece. All I did was stand there and blow bubbles, she did all the running around. The same thing with catch. I would throw the ball to her and she would run around, of course I could catch the ball she threw back to me, maybe you can be her proxy.
What about an activity at the table, or with him in a highchair? This way they can interact face to face. One activity that I do with my mommy and me classes is pudding painting. It's a safe way to introduce finger painting, and a sensory activity ( that children your child's age LOVE). It can be done with any flavor of instant pudding and some construction paper. Just put a dollup instant pudding on the construction paper and have your MIL show him how to "mush" it into the paper. If he eats it, he won't be harmed. So let baby go wild. MIL can also help him to make shapes and letters on the paper. Then when it's all done, she'll have a piece of art to hang on her fridge made with love by her grandchild. Once the pudding dries on the paper a good shellacing with aerosol hairspray helps to preserve it for a few months. Just an idea. Good luck!
