Tents can be made almost anywhere. If you can, camp outdoors with your child in a real tent. You can also camp indoors by using your imagination a small table can be set up wherever the tent is to be built, and just put an old sheet over the table. Be sure to stock the tent with an emergency supply box:
A flash light (torch)
Some games or toys
A couple of pillows
Snacks
And anything else you might need
Monster time
For extra fun pretend there is a monster outside. Your child can take turns with you pretending to be the monster. Peek out when you think the monster has gone away. Make friends with the monster and offer the monster a snack.
