In two days, my baby girl will be 5 months old. I don't want her to become obese, so I'm trying to control her weight gain even though I breastfeed her. She's growing so fast. The doctor said she should only gain around 500 grams per month, but she's gaining 700 grams. It's okay, one more month, when she turns 6 months and starts eating solid foods, her weight is expected to start decreasing. Chubby babies are cute, but I also don't want her to carry too much weight on her body.
