This video is awesome. This should definitely be incorporated into a lesson plan in 7th grade health class, then again, it may be best to explain this to your kids while they still think kissing is nasty, especially being that nowadays children are becoming more sexually progressive at younger ages.
Moving on.... The truth about how babies are really made, I must interject. 1) I would love to see a woman that smiles while she is delivering a child. 2) I would love to see a belly that goes down that fast.
