My FIL has been a bit of a challenge to me over the years but this one is niggling right now. He is a very fit, young GF. This is relevant.
He's not interested in DD at all really. Doesn't want to Skype, has to be arm-twisted to visit, not really great when here. I don't really care. Late MIL was the DC loving GP and now she's gone, he isn't really bothered.
He is pretty obsessive generally and I believe probably has NPD. He has a different MH disgnosis. He has said some pretty damaging things to various people including his young GS (SIL's DS). His current thing is to go on about how pleased he is that DD (3 yo) is thin. She's a tall, tall girl and even though she eats like a gannet, because she is active and tall, she burns it all off. FIL and DH talk about it on the phone a lot. I know DH wants FIL to be interested and proud and his obsession with fitness and size means this is a way of connecting about DD. I hear FIL changing the subject whenever DD is brought up except for this subject.
I feel really uncomfortable about DD's weight/size/slimness being touted as a positive like this. Particularly as the only positive FIL will talk about. She's 3 and she works really hard on lots of stuff; manners; being kind; sharing. She tries hard and feels proud when she helps out, tidies up, is gentle and kind. Her size is just an irrelevancy. Not important, not something we need to address, not something that she has any input into (I choose her food, she chooses how much).
DH is REALLY sensitive about anything to do with FIL. Total FOG. He thinks I don't like FIL. I actually quite like him (he's funny and interesting) but really don't trust him. Do I leave it and make sure DD knows her size is immaterial to her worth, chalk it up to one of a million bad messages she will get about this in the next few years, talk to DH, talk to FIL?
NCed just in case. DH knows my NN.
