I danced while pregnant with my first child, and took class until the day she was born. Strangely she is the one least interested in dance of my three children! What I would like to pass on is something that the doctors did not tell me, even though I advised them of my dancing. As you get bigger, you should omit the jumping, especially during the last trimester.I actually had my daughter prematurely although I am not sure if the jumping contributed to this. As for recovery, I remember doing class with the baby in a carrier next to me at the barre- I had a very understanding teacher. I does take a while to recover, but like was said earlier- every pregnancy and birth is different, and the recoveries are also individual. Big milk filled breasts are another challenge, especially if you're not used to big breasts. If you are in good shape when and during pregnancy, and have a non complicated delivery I would imagine you would be back at class within a couple months, but I am not a doctor.I think age is a factor in recovery time also. The real challenge for me came later when they would cry when I left the house. I did give it up for a while, by choice, to be with my children, I was never professional or anything anyway, just dancing for fun. Now that my kids are older I am back, and am enjoying and appreciating it more than ever.
