self inflicted bite wound

Poor Josh just learned to look at his food and pay attention to what he's doing at the table when he bit his own finger during lunch. When I pick him up at school he usually tells me right away about the snack for the day and a close second was about a fire drill they had at school today. He was sitting here with me wrapping up lunch and talking about the fire drill again when he started crying and he actually made his right index finger bleed. Both of the boys have been sitting at the table lately crossing their eyes and saying"two Mamas" or two cups" I'm not sure if he was trying to do that when the incident occurred but I wouldn't be surprised. As far as I saw he just kept eating when he came to the end of the green bean he was munching. After he bit himself I decided to show him how to look at his food while it's coming toward his mouth and he put his head so low that he ended up with bits of hard boiled egg from the trays they use for meals on his fore head. It's really hard for me to keep a straight face right now - but I don't want him to start doing it on purpose to get the laughs. Right now instead of using his hand to hold down the bunch of grapes he's eating from he's draping his while arm over them so his finger doesn't hurt while he's pulling grapes off with his other hand. It took me a little while to figure out what he's doing but he says that's it. Ya live and ya learn: Don't bite your own fingers while eating.
