Wheel in with babies?

[Jessica Pierson]

Hey Everyone,     My little family unit is doing wonderfully, the babies are now 4 weeks old, and healthy as ever, and I'm expecting the new little any day now.  I just have one question:  I put the wheel back in today, much to mom and dad's enjoyment, but I'm scared that they'll get hurt somehow :/  Like when mom or dad are running, maybe they'll come over and get hit in the face?  Or maybe I'm just paranoid?    Thanks, Jess
