What are antenatal classes? Depending on where you live, your local hospital or birth centre, where you plan to give birth, will offer some sort of free information about your health during pregnancy, the birth process and your options for pain relief. However, there are other specialist antenatal classes in London, N1. Yoga antenatal classes, NCT antenatal classes, Yogabirth ante natal classes, Birthlight antenatal classes and hypnobirthing classes. Each offer a tailored approach to keeping you fit and well during your pregnancy and prepare you for a more informed birth. If you have time we'd love to hear your reviews of antenatal classes in London too.
