Eating...!

So anyone that has children knows that babies go through the stage where EVERYTHING goes in their mouth... They could stick the most nasty thing in there mouth and not have a problem with it at all. I have heard SOOOOO many stories of little ones putting some crazy things in their mouths, or even eating it lol. So today I went over to my mom's house to look for a few things, and it was just my son and I there. I was walking around looking for the things I was there to find, while my son played around. He reached up on the table and got a box with Santa on it, so my original thought was the box was harmless... So I went on about my business, a few seconds later I hear my son gagging... So naturally I turned to look at him and his little face was red and his eyes were all teary from gagging. So I stuck my finger in his mouth and tried to get whatever it was out. However in the process of doing that my son swallowed it... I later learned that he had stuck in his mouth a crayon and swallowed it :-( I felt so bad... This is the FIRST thing that my son has eaten like that, that I know of. He seemed happy and normal the whole day, so my guess is it didn't hurt him!
