DS1 (also 6) is going to a friend's party next weekend. We were in IKEA last week and bought our two boys (6 & 3) one of these each:
'Spook' glowing light
They don't really seem like lights - more like a rubbery toy/ torch sort of thing really.
DS1 loves his - and because it's rechargeable, he's been carrying it around the house, playing with it under his duvet at bedtime etc, hiding in cupboards with it etc etc.
I also bought another couple of them at the same time, thinking they might be good for presents, but now I'm wondering if people might think it's a bit of a weird gift??
