How often can a newborn drink formula?
My baby is seven days old.
Due to insufficient breast milk, I switched to formula feeding and currently give 60cc at a time.
How long should I wait before feeding again? Sometimes my baby wants to eat shortly after finishing, and I'm worried about digestive issues.
Also, I've noticed that the stool has clumps that resemble formula; is this normal? Do newborns need to drink water? Should I rinse my baby's mouth after feeding? I've heard conflicting opinions on this, so I would like to consult a doctor.
Thank you.

There is no specific guideline for how often newborns should be fed formula.
Some babies have a small stomach capacity and may experience spitting up, so they should be fed smaller amounts more frequently.
Other babies can tolerate larger amounts with longer intervals between feedings.
Generally, most newborns consume about 25-30 cc of formula per kilogram of body weight (for example, approximately 75 cc for a 3-kilogram baby) every 3-4 hours.
It is normal for their stools to contain undigested milk particles that resemble clumps of formula, which is not a sign of digestive issues.
Before six months of age, infants' kidneys are not fully developed, so it is important not to give them excessive amounts of non-milk fluids (especially for newborns under one month old), as this can put a strain on their kidneys and even lead to water intoxication.
After feeding, any milk residue in the mouth can be cleaned once or twice a day using a clean piece of gauze wrapped around a finger to gently brush the gums.
Therefore, newborns do not need to drink plain water.

More Info
Feeding a newborn can be a challenging yet rewarding experience, especially when transitioning from breastfeeding to formula feeding. In your case, since your baby is just seven days old and you are supplementing with formula due to insufficient breast milk, it is essential to understand the appropriate feeding practices for newborns.
Feeding Frequency:
Newborns typically need to be fed every 2 to 3 hours, which translates to about 8 to 12 feedings in a 24-hour period. Since your baby is currently taking 60cc (or 2 ounces) of formula, you should aim to feed them whenever they show signs of hunger, which can include rooting, sucking on their hands, or fussiness. If your baby seems hungry sooner than the 2-3 hour mark, it is generally safe to feed them again. Newborns have small stomachs, and they may require smaller, more frequent feedings.
Formula Amount:
At this age, the amount of formula can vary, but a general guideline is that newborns consume about 1.5 to 3 ounces of formula per feeding, depending on their weight and appetite. If your baby is consistently finishing their 60cc and still seems hungry, you might consider gradually increasing the amount to meet their needs, but always consult with your pediatrician before making significant changes.
Bowel Movements:
Regarding your concern about your baby's bowel movements, it is common for formula-fed infants to have firmer stools compared to breastfed babies. The "clumping" you describe may be normal, especially if your baby is adjusting to formula. However, if you notice any signs of discomfort, excessive straining, or if the stool appears hard and pellet-like, it would be wise to consult your pediatrician.
Hydration:
Newborns typically do not need additional water, as they receive all the hydration they need from formula or breast milk. Introducing water too early can lead to water intoxication and may interfere with their ability to absorb nutrients from formula. It is best to wait until your baby is around six months old before introducing water.
Oral Hygiene:
As for rinsing your baby's mouth after feeding, it is not necessary for newborns. Their mouths are still developing, and rinsing can be more of a hassle than a benefit. However, once your baby starts eating solids (around six months), you can begin to wipe their gums with a clean, damp cloth after feedings to promote oral hygiene.
In summary, feed your newborn on demand, typically every 2-3 hours, and adjust the amount of formula based on their hunger cues. Monitor their bowel movements and consult your pediatrician if you have concerns. Avoid giving water until they are older, and rinsing their mouth is not necessary at this stage. Always trust your instincts as a parent and seek guidance from your healthcare provider when in doubt.
