Find the Positive: "Hugging hands" instead of don't hit. "Walking feet" instead of don't run. Make up your own: "Whisper voice" instead of stop yelling. "Mommy's listening" for the whining times. "Love time" as a break when child is upset, fussy or clinging (then give your child attention and cuddles). Teach respect and proper communication techniques. Remember to keep your patience too :)
Obstacle course: wheel barrow to skipping rope, jump over, jumping jack to row of cones, weeve in+out of cones, walk over balance beam, jump between sticks (no touching), crawl through tunnel, find 10 scattered balls, shoot these into a basket, collect basket and run to the finish. Great ideas!
