Breastroke kicking is very different and a struggle for many kids. Remove all the other parts of the stroke and just work on the kick at first.
Most kids take too big of an arm pull in breastroke. Using the wall to limit the motion helps teach small, fast pulls.
The timing for breastroke should be: Breathe, Kick, Glide. By removing the arms, it keeps their motion small and fast, helping train proper timing.
We want kids to return to streamline with each stroke cycle. By taking 2 kicks, this forces them to spend more time in the streamline position and get their body position right.
We want kids to return to streamline with each stroke cycle. By returning to a full streamline in between strokes, this forces them to spend more time in the streamline position and get their body position right
Put it all together: Small kick, Small arms, BKG timing (breathe, kick, glide), Return to streamline.

Sometimes kids don't move their arms fast enough or glide too much. By taking out the breast kick, now there is no reason to wait and tempo can increase. Use with caution!
We want kids to drive through an imaginary Hula-Hoop in front of them, and to get their hips to follow through into the Hoop.
If kids kick too wide, forcing them to touch their ankles may teach them to keep their kick narrow and short.
