My husband noticed that LO has really bad breath sometimes at night. I had never noticed before until he had croup, which I wrote off to him having to breathe out of his mouth so much. Then, today I noticed during his late afternoon nap. Earlier in the day it was fine, but it was rancid in the afternoon.

About an hour ago he woke up screaming, which is pretty unusual. His breath is really, really bad right now. Is this normal for a baby his age? Could it be reflux or tummy troubles? He has 2 solid meals a day.

ETA: He is also teething. He has 3 teeth that broke through over the past month and 2 that are trying to break through now. I'm not sure if that could be the culprit somehow?
