Wracking our brains trying to think of a present for our 2YO DS's birthday next week. He's obsessed with vehicles, but we don't want to get him anything too big/plasticky/noisy. Thinking of a Brio train set, but the website says 3+. Is that just a cover-their-backs thing, or is it really too old for a 2YO? NB he's generally a very non-destructive child, and pretty dextrous.
