Oh hun, sending you lots of hugs . It sounds as though you are doing a wonderful job with your little girl . I can't imagine how stressful it must be to go through this over such a long period of time.

My DS was borderline IUGR, and borderline FTT for the first 4 months of his life. He was born at 35 weeks, so that complicated things a little bit in the early days. I found it to be so all-consuming, worrying about his weight and feeding all the time. For whatever reason, things picked up when he was about 4 months old (well, there were probably a few reasons, but I won't list them all here). The biggest factor we could find was when he was diagnosed as having cow's milk/soy/nut protein intolerances. The more he had of those proteins, the less weight he put on, and the more immune deficient he became. Especially past 12 months of age. Fortunately, it wasn't too long after that that he was diagnosed, and changing his diet made an enormous difference in many ways.

I'm not at all suggesting that this in any way relates to your lovely DD, just sharing my experience, and saying that sometimes there is often a reason for these things. Of course, figuring out what it is is the hard part. Sending you lots of strength and support as you continue this journey
