danger zone

Earilier today, the girls were jumping in their beds and so I told them that it was dangerous to do that because they could hit their head and get hurt. They didn't believe me so I turned it up a notch saying that if they hit their head hard enough, they could die!! So I went downstairs to do laundry and I heard this come from upstairs.." Come on Amelia, lets go hit our head to see if we die like mom said we would".
20 mins later they come downstairs with my phone to show me pictures of what they were doing....I should probably do a 'dry run' to the nearest hospital one day so that I know where one is 'in case of emergency'!!
