R.P.
Hello Stepphanie...I would take it away because it's becoming threatening. However, they need thier excercise to develop thier muscles in thier legs so I would get the Baby Einstein Discover & Play Activity Center or something similar to that nature. It is made by Graco and they cannot move about with it. This way they can be moved apart and get thier excercise as well. Here is a link to Babies R Us so that you can see what it looks like. Good Luck.
