What should Santa bring?

[bettydoc]

Advise me. 5 year old daughter and 6 month old son. Not sure what to get.

Something exciting like a new tent, assembled so both can enjoy together? fill it with balloons?

Also can work to give the 5 year old something you wouldn't normally, i,e if you don't like Barbie but she is desperate for one then Santa brings it - would make a child really happy
