My 1 week with 4 day infant only has one bowl movement twice a day . is that normal ?

Yes, a newborn infant can have a wide range of "normal" number of BMs per day. As long as they are not like hard pellets and they are drinking well and having 4-6 wet diapers (or more)/day. If you are breastfeeding, the BMs may be more frequent, smaller, and softer than with bottle feeding, but not necessarily.

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 okay, even if delayed.
