I’ve bought these for my youngest 2 this year. Being organised for once, they’re wrapped ready for Christmas Day. It’s just occurred to me that they may not be as ready as I thought... do I need to unwrap to charge them now? Do I need to set them up? I’m no good with tech and don’t fancy landing myself with hours of work setting them up on Christmas Day, but similarly if I can get away with leaving it for now that’d be great as I’ve loads still to do!
