A. Yes you can use diaper /pampers of any good quality brand. But not for the whole day. give diaper free time frequently in a day if possible use cotton langot, it will help to decrease diaper rash if any.  Always check every 2 to 3 hourly for urine and motion and change immediately once baby pass urine or motion.
