Obstructed bowels!

Well it happened 3 days ago Bailey did two realy hard stools then the next day he started having diahorrea then the next day after that the diahorrea continued and he started burping a lot and it smelt like faeces! It was disgusting but i thought he might of just had a gastro so let it go. During the night he vomited everywhere in the bed and it smelt really really bad. His diahorrea was really bad as well. I waited to morning and took him up to the hospital. Their diagnosis Bailey had an obstructed bowel and was very dehydrated not dehydrated enough to stay in hospital though. He actually picked up a bit while we were there. So we were sent home on strict orders to get his fluids up. About 2 hours after we got home Bailey did his "normal" bowel action. We have to see our peadiatritian about his bowels though because he has really had trouble with them since he was born.
