Obstacle courses are fun for adults, dogs and older kids, why wouldn't toddlers like them too? Guess what...THEY DO!
Use whatever you have around the house. You can use a large pillow to climb over, a box to crawl through, a chair or stool to circle around and finish with a run through a door or to something soft like a couch. You can add even more fun to the obstacle course by starting by blowing a whistle in the beginning and having a crepe paper finish at the end in a doorway.
Have fun with this and get creative!
