When I was little I had a mini-trampoline (I actually still have it!). I’m sure they say not to let kids use them now, but if you supervise it’s not very risky. It’s also good exercise for mommy. Walmart (I think) has one that uses elastic bands instead of springs, so little fingers can’t get pinched. It’s only about $40.
Also hula hoops are fun and don’t take up much space. Or just plain dancing.
Some random internet ideas:
It’s Never Too Late to Skate
On a carpeted area, clear some space to make a “rinkâ€. Get two pieces of paper (8 ½†x 11â€), and put one under each foot. With shoes on, stride forward and backward as if you were skating. Have skating races, create a path to follow or skate to music.
Time to Act
Act out a sport and have the child guess what sport you are “playing†(for example, basketball, hockey, soccer, baseball, volleyball, swimming). To make this activity more active, have the child mirror the activity while you act it out. Try again with another sport. Take turns acting.
Play Simon Says, and include little exercises in the game. (Simon Says, Do Jumping Jacks)
Indoor Hopscotch
Create an indoor hopscotch by sticking masking tape down on the floor. You can do this activity whether you have a carpet or a hard floor. Show your child how to go through the hopscotch. You can just take turns hopping straight through it. Or you can play a regular game of hopscotch, by tossing a small stuffed animal or toy onto one of the squares. The player has to hop through the hopscotch, hopping over the space with the stuffed animal on it; and then turn around and hop back, stopping to pick up the stuffed animal on the way. There are many variations of hopscotch games. Play your favorite way, or make up your own rules!
Bowling
Set up a few non-breakable items, and roll a soft ball towards them, just like real bowling.
Hide and Seek
Make a Fabric Wall
String a clothesline across a room. Pin old sheets, towels or pillowcases along the clothesline to make a fabric wall. Let your kids have a ball running under, between, and through the sheets.
“We also play ‘animals’ where we just go around the house, pretending to be different animals. It does wear them out crawling around like lions and cats and whatnot. Plus fast crawling when the lions chase each other”
"I play music… the best one is Polka music. As much as it annoys the hell out of me - the kids love it and will gladly dance around. I pull out my bin of stuffed animals and let them roll around in them too. Amazing how long kids will play in a pile of stuffed animals with polka music playing in the background " (That’s a hilarious suggestion!)
Hope some of this helps!
