During the 3 yr old's naptime the 5 yr old asked me, "Do you remember when Max put those things all over our room so we couldn't get out?" Let me decipher 5 yr old language. At Christmas, their Elf on the Shelf, Max, crepe papered their doorways at night.
Since it was "quiet time" and he had recently watched the Backyardigans where the girls are princesses stuck in a tower and they had to dance their way between lasers to escape.
Anyway, we put those two together and created his own lasers in his room where he had to move around his room without touching any lasers.
