Can I practice after delivering? How long should I wait before restarting?

First, you must have doctor cleareance before practicing anything other than savasana. In the first month after delivery you should restrict yourself to pranayama (taught by your teacher) which brings a balance between the body and mind and brings proper rest. Certain asanas help in recovery, even help to improve the quality of breast milk and bring a more restful postpartum experience which is usually devoid of sleep. Contact your teacher for more information.
