What kind of game can I play with my toddler to help develop his gross motor skills?

Toddlers love obstacle courses and you can create this one with a few cardboard boxes and some imagination. Collect several larger size cardboard boxes. Four should be adequate for this age.

Have your child help you decorate the boxes. He will be thrilled at colouring on the boxes and adding stickers. Now, open the ends of two of the boxes. These will become the tubes that they will crawl through. The remaining two boxes will be used in the obstacle course as objects to manoeuvre around. Set up the course in the middle of the floor. If it is a hard floor, it’s fun to use a masking tape to mark off the course.

Establish a starting place and a finish line and explain the course to your toddler. Show him how to go through the course; around the first box, through the first tube, around the second box, and so on. At the finish line, make sure there is a small reward for your toddler. He will feel a great sense of accomplishment for having made it through the obstacle course!
