Pregnancy and giving birth can have a big impact on your body and therefore also on your vocal technique. If you have recently given birth, there is no reason not to participate, if you feel you have the energy and motivation to start working again. Our voice teacher, Francesca also has a degree in medical vocology, so she is a perfect person to help you get to know your voice again and to take control of your possibly changing technique.
If you need to take your baby along to the class, please don't hesitate. The teachers themselves have two kids, and are very supportive to new parents. If you know that having your baby along will keep you too distracted, it might be a good idea to have someone come along to entertain the baby while you are singing.
