wow! Thanks, ladies. Unfortunately, there is no way to know why. And the area he is from (international), it is unlikely he spent any time in a nicu. No oxygen, no feeding help, no incubator. Just picked up, looked over at the hospital for a few days, and taken to the orphanage. Don't know if he's premie or IUGR. Mother unknown. He has been cared for wonderfully by the staff, but without much medical help. He is about 2years, walks with help, puts multiple words together, has the most captivating smile and has captured my heart... honestly, I'm not so worried about the physical issues, it's the congnitive and behavioral. I have four kiddos, one with special needs, and I wonder how much I can take on - but oh, my! he's beautiful! This is so hard.
