Should i be worried my one yr old is in the 10th percentile?

yes anything under 20 % is under weight

my 2 yr old niece is in the 1 percentile...just petite. its alright. i was over 100% lol just opposite ends of the spectrum

my daughter is in the 14th for weight and her Dr isn't concerned.... if the Dr didn't seem concerned then I wouldn't worrg

her pediatrician told me that doctors are only worried if they're under 5% or over 95%

I'd ask the doctors I think if they were worried they would mention something
