Over a pool noodle or through a ring

Hold a ring or pool noodle about one meter in front of the child at thigh height; the child dives through the ring or over the noodle. The noodle is soft and painless, a hard ring can be slightly uncomfortable — if the feet get caught, simply let it drop. Particularly useful if your child still carries the rotational momentum of a forward roll and tends to somersault during the dive.
