Am I the only one with a tiny baby?

We went in for a walk-in appointment today for a possible eye infection and my little girl only weighed 14 lbs 10 ounces. She will be 9 months on the 22nd. She has always been below 10% for weight and height, but I see all these other babies way bigger than her at this age. As a ftm I know I worry a lot, just wondering if anyone else is going thru the same thing. She was 6lbs 8oz when she was born and 19.25 inches. Last height check that I measured was 25 inches at 8 months. If you look at her you couldn't tell she was so tiny because she has rolls everywhere.
