It wasn't just any napkin -- it was a sanitary napkin. That was 2-3 weeks ago. He's eating and pooping just fine. I watched him and after about a week he vomited and up came half of it. I'm thinking the other half may still be in his system. He seems healthy, drinking more water than ever before for some reason. Suddenly, for the past week or two, he has been peeing in the house, including in the middle of the night while sleeping with one of the kids. I'm thinking there is still a piece of that napkin in his system soaking up so much water that he can't control his bladder when it has finally reached its limit. I'm scared to induce vomiting as I've read in some of the other posts only because he swallowed the object weeks ago. Do you think the uncontrolled peeing is connected to a possible half of a napkin in his gut somewhere? Now what?
