"exercise more." i know that. "try laxatives..." know. believe me. it's like i've. tried. everything! my chronic constipation keeps coming back. i know that. tell me something i don't know.

>> it's probably on the part of pediatricians to get the word out a little more about sids dangers. we have a lot of generational things that have been passed down over and over and over that we've gotten comfortable with doing that maybe we shouldn't be doing. >> reporter: the study also found when infants were moved overnight, most of the on the a parent's room, the new sleeping site was generally more dangerous. bed-shared is a risk factor for sids, and soft bedding objects may cause suffocation by covering an infant's nose and mouth. >> pelley: dr. jon lapook, thanks, doc. a gun scare sends passengers running for the exits. that's next. rheumatoid arthritis. and i was worried about joint damage. my doctor said joint pain from ra... can be a sign of existing joint damage... that could only get worse. he prescribed enbrel to help
