Tiny tot

Any other mommas have a tiny/petite little one? We had her 2 year check up and she’s only 20lbs 9.6oz, only 8oz more than what she was at 18 month appointment. And has only grown an inch since then as well. She’s 29.75 inches. She’s always been on the tiny end, never lost weight, and always hit her milestones a little earlier. They want to see her back at 2.5 years since she hasn’t gained a lot. I wasn’t concerned before and they hadn’t been until this appointment. Although we saw the NP rather than the doctor and she mentioned it one other time to me where the doctor has never been concerned. I’m only 5’ and dad is only 5’6”. Just curious if anyone else has a little one.
