I have a 27 weeker who is now 11 mons chronologically. She weighs 10 lbs 2 oz & is 22 1/4 inches long. She was maintaining her weight & now she's losing. We've tried many options. The ped is now suggesting to switch to formula for a couple weeks to see if that helps, thinking my milk isn't high enough in calories. I don't want to give her formula, so if I could just get my milk tested there would be no question. She goes in Friday for bloodwork, urine test, stool tests, EKG, Ultasound, & X-Ray.
I nursed my older dd until she self weaned at 29 mons. She's very healthy & never had weight issues.
