I have posted about this in the past. Brief (as poss) back story:
DSSs 15 and 12 with us every other weekend. We alse have 3yo DS. At the beginning of last year, it became obvious that MIL was treating DSSs differently to DS. She would hand them money and give nothing to DS. Repeatedly - every time we saw her. Then when we went to visit, this came to a bit of a head when she actually gave them drinks and sweets and totally left DS out. Literally, when we arrived, the other 2 were each offererd a drink and DS nothing. Then later the other 2 were sitting at the table eating chocolate bars while DS was asking me why he didn't have any, and could he share DSSs. DH (after I'd said to him) asked his mother not to do this.
She ignored him, and then on DS's birthday last year, MIL actually handed money to the DSSs and specifically said something along the lines of "and this is because it's not your birthday" - WTF? .
At that time, DH and I had a huge row because I was getting really angry about her deliberately making such a difference between them. DH said it didn't matter and that DS wouldn't notice. Also that MIL was doing this because he felt 'sorry' for DSSs. I said I didn't understand why an adult would deliberately disadvantage one grandchild over 2 others, out of some misplaced sense of loyalty. DS was starting to notice. Also it really is difficult enough in a blended family, without someone basically sabotaging all efforts to make sure the children are growing up without a clear difference being made between them. DH (somewhat reluctantly) pointed this out to his mother.
It appeared to have stopped. But, lo and behold, it was DS's birthday last week. All DH's family were at our house (including FIL - who is divorced from MIL). Everybody having lovely time. Then MIL, out of the blue, publicly hands £30 each to each of the DSSs for their holiday. Saying "DS will get money for his holiday if he goes on holiday at that age". WTF? DS then asked me why DSSs were getting money to go on holiday, and was he not allowed to go on holiday. He was basically very confused and I had to spend all evening answering questions.
When I posted about this last year on another part of MN, the overwhelming response was that DH needed to step up and tell her it wasn't acceptable. He reluctantly did this, like I said. People were of the opinion that this is likely to cause problems between DSSs and DS, certainly into the future, and that it should be stopped now.
I am so annoyed that this has happened again.
I think a mixture of shock, it being to public and it being a happy family occasion, that I didn't say anything. I could kick myself. The next morning when I woke up, I said to DH where is the money MIL gave to DSSs. (thinking we would either give it back to her and explain why, or just split it 3 ways like she should have done in the first place). But DH said he had already sent it home with DSSs
He then had a go at me for bringing it up.
Thing is, he gives his mother a fool's pardon. She has always treated BIL differently (constantly giving him cash, "poor xxx", etc etc) from DH and DH justs accepts this is the way she is. I think fine, but when that negatively impacts on my child, it shouldn't be tolerated.
WWYD?
