Bugs in My Legs

Last night while eating dinner, Cayden broke into tears, and appeared to be scared and in pain at the same time.  We tried to calm him down enough to understand him, and all we could make out was "bugs in my legs."  After holding him and trying to figure out what was wrong, he just kept saying that his foot hurt and that he had bugs in his legs.  He even said they were purple and yellow bugs.  We finally figured out that his foot had fallen asleep because of the way he was sitting in his chair.  We had quite a laugh, and got rid of the bugs by running up and down the hallway to shake the bugs out.
