I have been with my husband for 12 years. I have a 20 year old daughter who has high functioning autism so although extremely clever and able is emotionally and maturity wise more like a 14 year old. My husband is the only father she has ever known and he has done his best to be a good dad to her. Up until recently his parents have also been really good and seemed to enjoy being her grandparents. She was the only grandchild they had.
9 months ago my husband and I had a beautiful little baby boy. Our 2 hopes for him are that he grows up happy and that he has a close relationship with his big sister. My IL are over the moon and want to dote on him but it feels like it's at the expense of my daughter and I'm really worried about how it will affect her and ultimately how it will affect the two of them together.
For example my ILs have sent money over for our children for Christmas. They've very generously sent £50 for our daughter. But they've sent £500 for our son, so we can put some away for the future for him. This makes me very uncomfortable because I feel like it's setting up resentment for the future. I'd rather they sent both of them nothing than this. But then I don't know if I'm being strange in expecting them to treat both of them the same. I know there's no way my parents would do this if the shoe was on the other foot.
Is this normal behaviour that I need to get over or are they wrong to do this and if so, how should I handle it?
