I have a six day old baby who hasn't had a bowel movement since late friday night (it's now sunday) he isn't in pain. should i be worried?

Cautious: I would certainly make an appointment to see your Pedi soon. Many newborns have constipation as their nervous system is underdeveloped. You might want to try some rectal stimulation to help trigger an automatic relaxation of the anus to allow passage of the stool. If on formula, make sure you are mixing it correctly with water. DO NOT give your infant straight water tho. http://www.livestrong.com/article/171825-constipation-relief-procedures/

Normal: Breast babies can do a little smear every feed or a diaper filler every 7-10 days. Breast milk is a well designed food source compared to formula, where more debris is left over after processing. Bottle babies usually go at least daily if not more often. If it is soft when they go it is considered ok.I baby is playful and feeding okay you can just watch it and call the doc if it continues
