I think it was some kind of plastic sqweaky toy he ate. I just don't know. I'm so upset. I just talked to a co-worker and she told me he may have to have surgery if he can't pass whatever is plugged up in him. I was going to wait until 1pm to go home but I think I might leave at noon. It takes me 35 minutes to get home. I'll keep you all posted. Thanks for the suggestions.
