First day of Kindergarten Prep

Well the first day of preschool is almost over now, and Hunter was not in attendance. Last night he decided to do cannonballs off the couch. I guess I jinxed us after the first one by saying "no more, tomorrow is the first day of preschool and we don't need any broken bones." I turned my head and he did it again only falling straight to the floor after the jump, he landed wrong on his foot and now will not walk on it. Is this possibly Hunter's second broken bone, I hope not, we have an appt later to have it looked at.
