Petit kids

So I was just informed at my daughters sick visit that she’s in the .2 percentile. She’s about to be 3 and she’s only 24.4lbs. She’s a very picky eater. She drinks a lot of water and pretty much anything else we give her. Mostly water and milk. And she uses the potty normally. Her ped has told me she wants to get some blood work done for her. I’m kind of freaking out and wondering what could be wrong. She’s always been very petit. She was born 6lbs 8 oz and gained weight slowly. She’s very active, she loves to run around and play so she’s not like always sleeping or being lazy. My mom agrees I should go and get it but I just wanna get more moms opinions just in case. Anyone else have a very petit child? And have been in this similar position?
