Babies on exclusively breastfeed pass urine around 10-12 times in whole day(24 hours). 5 times is little less if that is in 24 hours. But if baby is feeding well and activity is normal then nothing to worry. At this age motion from 10-12 per day to once in 4-5 days everything is normal. At around 30-45 days nearly all babies get evening colic. They are generally happy and playful in morning hours and become cranky in evening and night.

Baby should pass urine at least 5 to 7 times a day and can pass stool with each feed or once in 3 days
