Within the first few days, your baby should have one dirty nappy for every day of life (which means 1 single nappy on day one, 2 nappies on day two, etc.). But as of day four, your little one should be pooping his diaper 3 to 4 times a day, or after every feeding, or even more often; that's totally normal as well.

P.S. The poop of a breastfed baby is usually soft to runny with some seed-like spots. Click here for more details.
