She's already very small. I measured her today, and she is 1/2 inch shorter than in October, and when she was measured at the doctor's in Nov. Is this really possible?
I posted another link about her a few days ago about her having pain in her chest area and stomach aches.
Really need some ideas, i'm worried.

How is her posture? Have her bend and touch her toes, and see if her back seems to be in a straight line. If not, have her go to the doctor.

What do you use to measure her with? Is it possible that you could have measured her wrong one of the times?

I measure her very regularly because in her second year of life she only grew one inch. She dropped from the 60th percentile to the 12th. The doctor seems to think it's a normal drop for a breast-fed baby, and that since she is retaining the 12th to 15th percentile, that she is fine. But I am beginning to think more and more that she has growth hormone deficiency. I have an apt. for her, but not til next Tuesday. I'm very stressed, as every time I measure her, I hope for a big growth spurt.
