DS is 6. My sister asked what he wanted for his birthday so I sent her a couple of suggestions. She replied saying she'd get him X so I replied dating he'd be thrilled as it was something he really wanted.
Last weekend was his party and a couple of the children have him cash which of course was burning a hole in his pocket so I took him to the toy shop. They had an X which he really wanted to spend the money on but I wouldn't let him, saying I was pretty sure he was going to get it today when we were meeting with my family.
Today we met up, had a lovely family lunch and then presents and my sister has got him something else. He was very polite and pleased with his presents but when we were on my own a bit later he asked me why he hadn't got the X thing.
I wouldn't have mentioned it at all but he's been going on and on about this particular thing for months (since before Xmas) and I've just kept saying 'wait till your birthday'.
I just think it's really odd behaviour on her part. AIBU? I do feel like an ungrateful wretch so happy to accept I am.
