How much should a breastfed baby poop and pee in the first few days after being born? is only one pee on the second day but no poops concerning?

Babies need to regulate their fluids in the first 24-48 hours of life. They generally have a good urine output during that time, and should pass a poop that is dark and sticky called meconium in the first few days. One pee is concerning as dehydration could be a concern.

The first day or two, the baby will lose excess fluid and may not take much in. By the third day, with consistent offering of the breast every 2-3 hours, the baby's intake will increase and the stool frequency will also increase. Best wishes and congratulations!
