DS2 is 10 and loves computer games, football and not much else.
DD is 8, she loves lip balms, stationery and hand sanitisers 
DD is going to be trickier re a BIG pressie.......
Any ideas re technology for DS2 would be good as I know very little about it, DH not much better.
Considering a go-pro, as long as it's veeeeeery easy to use!
