I think I AM being unreasonable, just to start with 
My DS is 5 and asked for a Nintendo Switch this year which was technically out of our budget so I warned him Santa might not get that but I got it anyway just to see his face as he was so excited and he's been so good.
But he's been barely fussed about it and complained about the games he got and that it isn't the colour he wanted.
I had a word with him about gratefulness and he seems to understand.
I guess I'm just feeling sad that his big present that was supposed to be super exciting has just not been that great to him and slightly irritated about the fact he doesn't feel really lucky to get it.
It's definitely a me problem but I'm really looking to see if anyone else has had a similar situation to reassure me
