My daughter was banned from playing hide and seek at the age of 4 because she hid so well it took us hours to find her and no amount of threats or coersion could force her out of hiding.
LOL... I had one child that hid that well, too!
The silly little girl would hide, and then go to sleep all scrunched up in the most impossibly small spots- had to search every box and cupboard!
Her favorite place to go to take her afternoon nap when she was four was a 2’x2’x3’ toybox... with lots of toys still in it.
