I went to Anoushka's Yoga -
www.anoushkasyoga.com - in Wynflete St Earlsfield. The Teacher Lon is fab. It was the one thing that kept me sane throughout my pregnancy and I really looked forward to each class. Lon also runs a mum and baby class so a few months later you'll get to meet up with girls (and the babies) you did the ante natal class with.
