It has been recommended to us, that we prophylacticly deworm our children twice a year. That really only means that they take a deworming pill every six months just in case they might have some type of worm.
Well, we did our deworming ritual on Wednesday night and we told the kids it was to get rid of any worms they might have inside their bodies and our 6 year old son said, "I haven't eaten any worms! That's gross." Our 3 year old responded, "No. I like eating worms! Snakes are gross." Maybe we'll start deworming him more often!
