No direct experience here but I have a few friends who were dancers before and either kept dancing or returned after. Many of them did feel there was a big difference. The return of feeling like it was before was different timeframes for each...depended on whether they kept dancing during pregnancy (less time), weight gain, natural versus Csection, and more.....seems to be pretty individualized from what I understand.....

Just keep encouraging her....it might be different but does not mean it is bad...just new with a new little baby too....so just keep her going!
