Ladies with baby in low weight percentile

Denise • Married young woman with two daughters
Hey ladies, I need some feedback/reassurance. I would like some feedback from the ladies who have a child that is in the low percentile for weight. My baby girl is 10 months and weights about 14 lbs. She is small, but very happy, healthy, and meeting all her milestones. I breastfeed and she is getting her solids daily. She doesnt take bottles and never really has. The doctor is concerned about her weight because she is not following the "growth chart". At this point I'm distressed...
