My little girl is 11 days old. She has been gaining weight wonderfully; 9oz in four days at her recent weight check. But I still feel myself concerned because her nursing sessions are only about 10 min long total or less. My let down is very fast. So my assumption is she fills up fast? She eats every 2-3 hours depending. Wet diapers average about 10 a day and 3-5 poop's depending the day. Anyone else have a baby do this?
