Big 4 month old daughter

My daughter is 4 months old and weighs 14lbs. She’s exclusively breastfed and eats on demand and everyone keeps mentioning to me how big she is including family and my doctor. They’ll make snide comments like “oh she’s so big she doesn’t look 4 months” or “wow she’s very fat what are you feeding her she looks 8 months old”. It’s making me so upset and very angry as I don’t see her or any baby as being big what am I supposed to do cut her feedings down ? Has anyone gone through this ?
