What was baby's birth weight? 7lbs 13oz
What is 4 month weight? 11lb 15oz (I think...may have been 11lb 9oz)
Breast or bottle fed? breastfed with a couple of bottles of pumped breastmilk a day to supplement
(If it applies) Did baby's siblings gain at about the same rate? No...they were WAY bigger by 4 months. Of course, most of you already know about her issues....she lost weight (a full pound) from 2-3mo and we're basically force feeding her quite a bit through the day and she's only gaining very slowly. Her three rounds of bloodwork, as well as her urinalysis, show several abnormalities, so we are waiting to see a geneticist. They strongly believe she could have a metabolic or mitochondrial disorder.

DH is a type 1 diabetic, and some of the things can point to pancreatic disorders for her. We shall see. Anyhow, she's not even 12lbs and her brothers were all around 16-18lbs at 4 months.
