I did prenatal yoga classes with Kasia from my 20th week to the end and I can truly say it was one of the best things I did during my pregnancy. I was trying to be a daily practitioner for some time before pregnancy and her lessons and weekly mails containing tips for home practice kept me motivated to continue daily practicing during pregnancy as well. The poses and especially breathing techniques she taught helped me a lot to relax and cope with the pain. Besides being a superb yoga teacher she creates a calming and friendly atmosphere in her classes which also made me to look forward to go the classes even at the times I was moody and you know you can be moody from time to time during the pregnancy ;)
I would definitely recommend prenatal yoga with Kasia to any pregnant woman!
