N.K.
BOTH of my kids were cranky and had the disgusting poop - ONLY when they were teething. My Dr., who has a daughter the same age as mine, said absoultely it's because of the teething and no amount of naysaying could get her to believe otherwise since she'd experienced it herself and there were no other reasons for it. I trust our Dr. completely.
Unfortunately, I've come to the conclusion that the newer they are to the practice the less they know.
Not only that, it also seems that they are more and more likely to dismiss anything that parents are concerned about.
Do they think we're stupid? We know our kids better than they do and we know when something is wrong - even if it doesn't show up in a blood test or exam.
