How true are they to size as per the pounds recommendation? I am looking to order my first ones to try with woollies during the day and not sure what size to get. My LO is around 18lbs, about 30", and super skinny....as in skinnylegs, skinny waist. She is 12 months old and really the waist of 6 month pants would fit fantastic, if only the length wasn't so darn short.
They say med is 14-23 and large is 21-30lbs. Any recommendations on what size to get?
