A 3 day old should have at least 3 to 5 wet diapers a day and between 3 to 4 poopy diapers a day.
However the amount of wet and poopy diapers in the baby can vary.
The wet diapers the 3 day old has will often be clear or pale yellow in color and the poopy diapers for a 3 day old may transition from black, tarry "meconium" to a greenish-yellow color.
If your 3 day old or older age baby has less than 6 wet diapers a day after the first week of life or the baby shows signs of dehydration you should contact the baby's pediatrician or if the baby is severely dehydrated take the baby to the ER.
Newborns should have at least 3 to 5 wet diapers on day 3 of their life.
The newborns urine color should be a clear color or pale yellow color and dark urine can be a sign of dehydration.
If you breastfeed your baby, your baby will produce more urine and have more wet diapers as your milk supply increases around day 3 or day 4 of the baby's life.
A 3 day old baby should have around 3 to 4 poopy diapers and the poop should be in a transitional phase, which means that the 3 day old baby's poop changes from a black, tarry meconium to a greenish-yellow color.
Breastfed babies also tend to poop more than formula fed babies due to the composition of the breast milk.
Breast milk is more easily digested than formula as breast milk contains a high proportion of whey protein, which helps to promote rapid movement of food through the baby's digestive tract.
The breast milk also contains lactose, which is a sugar that can also cause frequent bowel movements in some babies and the low fiber in breast milk also can allow for more efficient digestion and frequent bowel movements and pooping in babies.
And babies that are breastfed are also often fed more frequently than babies that are formula fed, which also stimulates the baby's digestive system and results in more frequent bowel movements and more pooping.
Breastfed babies in the early weeks of their life are also developing and growing rapidly, which also requires a lot of energy and also a lot of nutrients.
The increased metabolic activity during the rapid development and rapid growth in the baby also contributes to the more frequent bowel movements.
Some breastfed babies may have several bowel movements or poops a day, and other breastfed babies may only poop once a day or once every few days which is normal.
As long as your baby is gaining weight properly and they appear healthy, the frequent pooping is not usually a cause for concern.
Even factors like underlying medical conditions, maternal diet and use of antibiotics can also influence the amount of bowel movements or pooping that the breastfed baby has.
Breast milk is very highly digestible in babies and the lactose content, lack of fiber and the frequent feeding of the breast milk as well as the rapid growth and rapid development in the breastfed baby all are what contribute to the frequency of poops and bowel movements your baby has.
