I forgot to mention one of the coolest things we learned about kangaroo care. Apparently, it's essentially been done for a long time in countries that don't have the highly developed NICU's we have. When a preemie is born in a developing country, they often use kangaroo care to keep them warm, and their life depends on it. Often, the babies will be passed from person to person, including family members and volunteers. How cool is that? In this sense, it literally takes a village to raise a preemie!
Here are some pictures of our kangaroo care:
