Having a new little one in the house I am once again in awe of how perfectly God orchestrated children and parents attaching and bonding to one another. Everything a parent does for their new baby releases hormones which provide neuro pathways to develop in the infant's brain. These hormones cause physical, emotional and intellectual growth.
Children who live for extended periods of time in an orphanage will not grow in height at the same rate as children in a family setting.
Here is what the Bucharest Early Intervention Study found http://www.endowmentmed.org/content/view/395/35/
The study has been running for five years and records the wellbeing of children in a Romanian orphanage from an early age, and the changes they experience when transferred to foster care. The orphanage represents an extreme of social deprivation because the children are typically looked after by a rota of carers who will be responsible for 12 to 15 children at any one time.
Researchers found children living in deprived conditions suffered stunted growth, falling within the shortest 10% for their age. But on moving to a foster home, they went through astounding growth spurts.
"They can grow five times faster than normal and by the time they've been in foster care for a year and a half they will nearly have caught up," said Dana Johnson, professor of pediatrics at the University of Minnesota, who estimates children in orphanages lose one month of growth for every three they spend there. Even though the children go through extraordinary growth spurts, they tend to go through puberty younger and faster, and so miss out on the usual long spell of growth most children experience.
The researchers say the children's recovery is unlikely to be explained by better nutrition as they had adequate meals before. Instead, they believe the effect is down to the more attentive environment.

Our son who spent the longest time living in an orphanage has experienced an incredible amount of growth since coming home.
He was 3 at homecoming and here he is with our other son (also 3)...

Here you can see he came up to about our bio son's shoulder..

Here he is today. They are almost the same exact height. Isn't God amazing? We are so blessed to witness al that the Lord has done in our sweet boy's life..AND
We are praying for all the millions of children throughout the world to find their families, so they can grow and thrive.
