Slow down little monster

My little girl rolled over from belly to back. Now, I don't know if it really counts as rolling over on her own, she was in her crib and I had her on her tummy so I could brush her hair after her bath. She may have had a little help with the softness of the mattress...but of course, as a mother, its a huge deal to me. Lol. She love bouncing, so I'm beginning to think that its time for one of those bouncer things, the ones that the baby stands in and jumps and plays with toys. She still loves her play mat, but I think it gets boring quickly because she is laying down and would rather sit up or stand. She is just growing so dang fast!
