At one week, feeding is on demand and wet-diaper counts are the key health signal.
Usually 6 to 8 wet diapers.
Around 3 to 5 per day, though this varies a lot.
Every baby is different. These are typical ranges for healthy, full-term babies, not targets. The easiest way to know your baby's normal is to track a couple of weeks and look at the pattern.
