I'm just typing this out really to get it off my chest and as far as issues with inlaws go it's not a big one. But MIL and you could also say FIL forgot to send DH a birthday card this year. He got a text to say sorry not even a phone call.
I suppose it was probably inevitable as they have forgotten both DS and my birthday for the last 2 years. I just feel so sorry for DH who has family who can't be bothered with him. We have tried so much over the years to make an effort but I've given up since the kids have been teenagers as inlaws just never bother and I got fed up off being the only one doing all the organising. So we hardly see them.
