Foxyroxy - Op I think you're getting a hard time from some here!
I agree. I dont give to receive, but if I was in your position, I wouldn't go out of my way to buy the children presents.
We generally only buy for children now, but in general all have at least one child to buy for.
I do buy for a few friends - One of which is my DD's childless-by-choice godmother. Athough we had always bought each other, when she started buying for my kids (she also bought DS until he turned 18) I made a point of spending significantly more on her present than in the past, knowing that she was buying for three and me for one.
Similarly with DS godparents, who have only one child and a much lower income than us. Whilst we tend to spend similar on the kids, I usually also buy them some nice chocolates, so it evens things out a little.
Your siblings sounds like my twat of a DB. He has stopped buying my kids presents on and off over the years (usually when he wasnt getting his own way with things - this is a late 50s man!!). When he stoppped for good and I decided to do the same, he had the gall to text me and remind me of his DDs birthday. He also sent some none-too-subtle hints near her 21st, which I ignored. Some people, esp siblings, are just piss takers.
