Postpartum Weight Gain

Danielle
Hello!!
I was wondering if any of the mommys here have had trouble with weight gain after your baby was born? I am breastfeeding my 14 week old and since she was born I have gained almost 30 lbs. I have tried everything and the weight still seems to pack on. Could there be something wrong with me? Is breastfeeding causing this? I appreciate any advice you have 😊
