Maybe it's because I have a 16 month old son that this video hits so close to home.  I just about lost it with tears of joy watching this little guy taking his first steps with his new prosthetics.  

He had his right foot and his left leg amputated because of a birth defect back in January.  Here we are just 6 months later and this little guy is up moving around.  Wait for the 1 minute mark where he starts yelling " I GOT THIS!"  Love it.
