It's ds's birthday soon and I'm slightly at a loss. I don't want to spend much - I'm going to give him a couple of the things that his sister used to have (walker, mega blocks) and he clearly won't care if he doesn't get anything at all, bless his little cotton socks, but I'd like to buy him something small, as long as it isn't going to disappear into the tidal wave of plastic tat that threatens to overwhelm us regularly despite the fact I cull it every couple of weeks. Ideally something that his sister won't run off with, as well...she operates on the "what's mine is mine and what's his is mine" principle. He'll get books from all the relatives, it's what they do, and in any case we must already own almost every book ever written for small children.
Inspiration, please?
