Query: Too slow!

We purchased this swing because of the plug-in feature (we were spending so much money on batteries for our Graco swing). It's an adorable swing, but it swings way too slow for our "daredevil" little girl. We had to take it back. I guess we'll just keep buying batteries. Too bad Graco doesn't make one that plugs in!
