It takes plain simple logic -- What goes in has to come out! The output on his diaper means you’re doing a good job. If your baby is getting 4-6 wet disposable diapers a day by the fourth day after birth OR 6-8 wet cloth diapers – your baby IS getting enough milk!

As your baby grows beyond the first month or so, the baby's wet diapers will be even wetter
