Just a slightly different perspective, on the view of the kids getting so much. I am also on a young mothers forum (not mumsnet) and there was a similar thread on there. The mums were saying that they had not actually bought much, if anything for their children, but they had got an egg from each set of grandparents, one from each aunt or uncle and a few from neighbours or friends of the family. So everybody, much like most of us on the thread, had spent a fiver or something along those lines, but with the amount of people in each child's lives, it had grown into a tremendous haul.
Maybe a good idea to talk to the mother of the child for future, and find out if they need anything, money better spent when so much chocolate is coming their way from a variety of different sources.
