My baby is 4 month old.. I have gained soo much weight. When should i start exercise. How to reduce weight.

A. Dear ma’am, you can do brisk walking. Split into half an hour in the morning and evening. Make sure to drink at least 3 litres of water daily. Add veggies to all 3 meals. Get adequate sleep and rest. Cut down white sugar, Maida and aerated drinks.
