I have 2 DC very close in age (under a year between them) and they have both asked for the same 2 main presents. Both presents are electronic type things (think a camera type device and a game type device) and both cost around the same amount.
Aibu to suggest that one of them asks for the camera thing, and the other asks for the game thing and they can share between them? They are 6 and 5 yo and are generally good at sharing.
Last year they asked for and both got the same main present, but they have rarely played with them at the same time throughout the year so I feel it would be a bit of a waste to do it again. Plus, obvs if they get the different gifts to share then they can ask for 1 more gift each.
