thanks all again
I had no idea I would have so many other opportunities during school (he is my only son) so that alone makes me feel better!
It turned out I misheard DH on the phone - it wasn't a dragon, they got a knight costume. DS loved it, so no point in changing it and tbh there is not much room for improvement either, but that's fine as he was really happy with it.
I didn't say no because MIL leaves the other side of the Atlantic and sees DS twice a year so she doesn't have many opportunities to spoil him. She knew I was trying to make the costume, but I do not think she realizes how much I actually enjoy doing things like this. She even said that 'I do not have to stress about it now', so she probably though she was being helpful. Plus she is prob the type of person who thinks shop bought costumes look better. I guess DH called to ask but also to warn me.
kingsdolstail Funnily enough I was going to tell DH to stay away from the costume section of the shop as I thought MIL might be tempted. We had a little raw just before they left and I didn't want to talk to him in the end.
And also, absolutely, a part of doing it (and doing it with my son) is to show him we really do not have to buy everything.
But it is also true, as you and seacabagge suggested that I do lack assertiveness, and that's probably why I felt so upset at the time.
bubbinsmakesthree it was going to be a fire breathing dragon...but I hadn't thought of sound effects! Fab!
Anyway, I decided that if I still want to give it a go, I will be the dragon.
