About this tool

This tool helps parents of breastfed newborns check whether their baby is getting enough milk by looking at wet and dirty diapers, feedings and weight.

Following AAP guidance, babies usually have 1 or 2 black, tarry poops a day on days 1 and 2, at least 2 greenish-to-yellow poops on days 3 and 4, and at least 3 to 4 yellow, loose poops a day by days 5 to 7. By 5 to 7 days, expect 6 or more wet diapers a day with pale yellow urine. Babies should breastfeed 8 to 12 times a day and lose no more than 8 to 10% of birth weight before gaining again.

You can enter today’s counts to see whether they fit, and the tool lists the warning signs that need a call to the doctor.
