WATCH: Little boy has a VERY important question for his new baby sister

This very little big brother is over the moon with his new baby sister. Just before they leave the hospital, Mom and Dad finally allow him to hold her. He carefully checks to make sure everything he expected to find is present and correct; there's two arms; two legs; a belly, but wait... one thing is missing. Watch these parents try in vain to hold in their giggles when their son asks a hilarious question as Dad keeps the video camera rolling. We suspect this tape may be dug out for his 21st birthday. https://www.youtube.com/watch?v=RjLEGHPvnmQ
