To try "mommy & me" or not to try it!

So let me know what ya'll think.......
Kendall is not going to be able to do sign and sing anymore since the lesson is going to be the same one that we just completed so I was thinking about keeping her in kindermusik but enrolling her in a "mommy and me" gymnastic class the hour before it. I have heard that some kids had a harder time transitioning to a regular gymnastic class by themselves after doing mommy and me. What is your opinion on it? Let me know :-)
