When you become a parent, you might find yourself obsessed with personal hygiene – not yours, but the baby's. You'll walk out the door with your hair looking like it's been electrocuted, but your baby will be snot-free and in a clean diaper.

Your heightened sensitivity to Baby's hygiene and personal care may lead to panic attacks when your breastfed baby seems to be having too many bowel movements – or not enough. To avoid the stress, here's a handy primer.

The first thing to expect is that initially, both bottle- and breastfed babies will pass rather unique first stools, called meconium. These stools are thick, sticky and greenish black, says Maureen Brown-Ginsberg, a registered nurse and International Board Certified Lactation Consultant at Women & Infants Hospital of Rhode Island. Baby will likely have one to two stools on the first two days of life. Around the third day, you'll see transitional stool, which is greenish brown and will be softer. Two a day is typical for this time.

During day four, Brown-Ginsberg says there will be a color change to a mustard yellow color. Baby will probably have three stools on days four and five. The seedy, mustard-colored stools will continue from day six through the first four to six weeks. Four a day is average.
