As everyone has said babies sleep while getting fed..but if the peeing is ok and baby doesn't get up and cry just after sleeping time and again it means baby is content..

Three week need to be fed for every two hour. Baby at this age sleeps lot. Try feeding them every two hour. If pee count is 6+ it means your baby is getting enough milk. Also check for hunger cues, can check on google for that.

It is almost impossible to judge if baby has taken enough milk in each feed. Over a period of 24 hours if baby passes urine minimum seven times then we say the intake is adequate. Over a period of a few days of stools are yellow in Color then also we are satisfied with the milk. And then add to both the above the weight gain should be on track as per the WHO growth charts.

Yes as Revauthi said if the baby sleeps for an hour it two and the pee count is above 6 baby is getting enough feed.

Hi
If your baby sleeps well for an hour or two, pees for six to seven times a day, then it's a sign of well fed baby. Tc
