Sorry I know these threads are a bit annoying. I have 2 boys who are the least obsessive type of kids I know, when I was little I was obsessed with 1 or 2 things and my mum could base the whole of Christmas around those. They literally haven't asked consistently for one thing, if I show them a catalogue they half heartedly point at everything but forget 5 mins later. I don't want to buy for buying sake but I don't tend to buy throughout the year for them so it's a good time to "stock up" for the year! Plus I have family constantly asking!
Sorry waffle over, what are you buying your boys? What are they asking for?
