Learning to somersault can be daunting for your child. It can help to bring lots of patience and have a safe soft floor to practice the trick.
Start crouched low to the ground with one foot in front.
Tell your preschooler to glue their chin to their chest. Even pull out some imaginary glue so they can remember.
Encourage them to 'kiss their back foot'. The goal is to try to complete the somersault without touching their head on the ground.
Gently push their back foot towards the direction they're rolling. Over time, encourage them to kick this foot off the ground.
Only give one piece of advice at a time. Once they seem like they've mastered that tip, give them another one.
