Husband has a sister who has a son and daughter. We have 2 sons and a daughter. MIL frequently favours her daughters children and spends lots of time with them. My children often feel like an afterthought. Most recent issue was halfterm. My MIL does not work, she chose to spend 3 out of the 5 days in the week of halfterm with her daughter and daughters DC. She didn’t ask me to come along on their days out and didn’t call or text once to arrange something with my children. Previous halfterm I asked her to spend time with myself and my DC but she had plans. She also spent time with her daughter and daughters DC that week too.
When she is around my children (when we take them to visit their gran) she is great with them and seems to care about them. Other than that she doesn’t make any effort. It is the noticeable favouring of the other grandchildren that hurts my feelings. For example she recently took her other grandkids out to the cinema, when I made it clear that my sons would have enjoyed going to the cinema too she gave me £10 to take them to see a film. The point I was making was that I wanted her to spend time with them, it seems to go over her head though.
I don’t think that she is completely oblivious to the fact that she spends more time with sister in laws DC though because if I ask her what she’s been up to (when I know she’s been out with sis in law and children) she will change the subject and will miss out the parts where she’s taken the kids out.
we have butted heads over the years over similar issues and it always ends in tears, she doesn’t take criticism well and I’m afraid of the arguments if I do speak my mind.
