This past Wednesday while I was trying to clean the house, I heard frustrated cries coming from my son's room. He was trying to make a tent on his bed using baby blankets and wasn't having much success. His bed. . .
Yes, my son is 4 & 1/2 years old and the Fisher-Price Rainforest Musical Mobile (complete with dead batteries) is still attached to his bed.
Using a queen size sheet from my thrifted stash and a few clothes pins, we created this for my now-happy camper. . .
He played in it quietly for a good 30 to 45 minutes, and it only needed a few minor repairs during that time. If you don't have a bed like this, you could use a simple card table to create your own fort/tent.
