I’m taking part in the met police gift appeal where you can sign up to buy presents for kids who may not otherwise receive much at Christmas. I chose to buy for three kids - and I got allocated boys of 10, 11 and 13. My kids are girls and much younger and I have no idea what pre teen boys are into. Is lego too childish for that age? Any ideas to help me get them something nice would be much appreciated. I could go for vouchers (argos? jD sports) but I think it’s nice to have something to open. Price limit is 20 quid. Help!
