A. Ma’am workout is good for you but during the time of lactation we don’t suggest but if it was a normal delivery you can start with basic Yoga like Surya Namaskar and all start having food which is healthy for you but in moderation if you have follow a healthy diet suggested by a nutritionist it will help in maintaining your breastfeeding and strength and stamina will help in reducing your weight so please talk with the doctor because it’s early time for you to reduce the weight on the mummy tummy
