The Frequency of a Child's Movement

For a child it's going to be basically the same. The frequency or I guess we'd say that the frequency will be the number of times they do that in a minute or whatever. But you're not going to want to push them every three quarters of a cycle or every third cycle. That would be non-resonant addition of force. Your energy wouldn't be resonating with the natural frequency and therefore you’re not going to really get anywhere.
