My son was born at 29 and a half weeks. He stayed in the NICU for 16wks. He was diagnosed with a grade 4 brain bleed, which delayed his bottle feedings and was eventually sent home with a G-tube. He is now 3yrs old and is doing well with his motor skills. My husband and I are amazed, as well as his pediatrician, for his overall development. When my son was about 8mths-1yrs old, my husband noticed one leg, foot, and arm being longer than the other, as well as bigger. We find that this has affected his balance when it comes to running- he still tends to fall on a regular basis. He has been wearing shoe inserts to correct his feet from growing outward. He has a very strong upper body and none of this seems to affect his will to do sports, but no one seems to have an answer as to why this is all happening. I just need to know what kind of doctor I need to start looking into before the situation gets worst. Thank you for your time...
