Michelle~    Hi, 2 of my 3 daughters are swcah. Kaylan our 3 1/2 year old  is pretty small, 37in’ and 30 lbs., but Sara our 10 mo. old is 16-18?lbs and 25in’. So K seems smaller than peers but Sara is pretty comparable. They have both been in the lower %’s for hieght & weight, but K’s bone age is right on. Many parents say the circardian dosing schedule helps tremendously with growth. I would definitely try it. I would not be too concerned if she otherwise it healthy, K is always in smaller clothes than her age indicates. Anna our 6yr old (non cah) is pretty tall, 48in/4ft she is already in 6x & 7pants and 7/8 shirts so I don’t think clothing size means much. She won’t actually be 6 until the 6th of next month!  Hope this helps.
