Middletown's own Winston Moore couldn't hold it together when his dad, Pedro, showed him the letter "M" is also a "W", when flipped upside down.
The video of the nearly 2-year-old's infectious giggle has been seen by millions since it was posted last week, in part thanks to shares from actress Jennifer Garner and Oprah Magazine.
Mom, Keira, says the family has been completely overwhelmed by the attention and heartfelt messages from across the globe.
She says they tried to have children for five years and are just grateful that their miracle baby is bringing the same joy, to strangers, as he brings to them.
