Mil says my baby is over weight

So my baby is 5 months turning 6 months in 2 weeks. She was born a month early and weighed 4lbs 5oz. My baby girl weighed 13lbs at her 5 month appointment and is now currently 16lbs. My BF sent over a picture of our baby to his mother and she said “ stop over feeding that baby. How many times are you feeding her a day? Let her sleep and stop waking her up during the day to feed” And then later sent a link about obesity in fat babies with a message saying “ don’t be mad I’m just very concerned about the baby.” She’s made many comments about my baby already ever since she was in my belly saying that the reason she came out small is because of drugs or pills bla bla bla. Idk but that’s just one of many remarks that have been made. I’m so done with her I’m ready to tell my man that I’m not going over for visits anymore. Anyways, Here’s a picture of my sweet baby girl ♥️
