Should I wake my newborn to feed?

In the first few weeks, yes. Wake your baby to feed at least every 3-4 hours until they are back to birth weight and gaining well. Once your pediatrician confirms steady weight gain, you can usually let them sleep longer stretches at night.

How do I know if I am overfeeding with a bottle?

Babies can take more than they need from a bottle because the flow is easy. Watch for fullness cues, pause often, and stop when they turn away or slow down. Normal spit-up is small and gentle. But large vomiting is not always a feeding-technique problem, so do not assume it is overfeeding. Get urgent care or go to the ER for forceful or projectile vomiting (especially after most feeds around 3-6 weeks), green or yellow (bile) vomit, blood in the vomit, or vomiting with a hard or swollen belly. These can be emergencies, not feeding issues.

My breastfed baby wants to eat constantly. Is that normal?

Yes, especially in the early weeks and during growth spurts. Frequent nursing is how babies build your milk supply, so 8-12 feeds a day is expected. If you are worried about supply or weight, check wet diapers and call your pediatrician or a lactation consultant.

How Much Should a Newborn Eat? At-a-Glance Amounts

Is my baby getting enough milk?

In the early days your baby's stomach is the size of a marble, so small, frequent feeds are normal and enough. Feed on demand, watch for fullness, and steady wet diapers tell you it is working.

Signs your baby is getting enough

Day 5 and beyond: at least 6 wet diapers a day
Regular stools (color and number shift in the first week)
Back to birth weight by about 2 weeks
Baby settles and seems content after most feeds
You hear or see swallowing during feeds

Reading fullness: when to stop offering

Turns head away from breast or bottle
Closes lips or stops sucking
Hands relax and open, body softens
Slows down, drifts off, or seems sleepy and calm
Pushes the nipple out with the tongue

Call 911 now if

Baby stops breathing for more than about 20 seconds, or any pause with blue or gray lips, face, or tongue, limpness, or no response
Blue, gray, or dusky color, or gasping for air
If baby is not breathing or not responding, call 911 and begin infant CPR now; the dispatcher will talk you through each step
Green or yellow-green (bile) vomit, or vomit with blood or that looks like coffee grounds
Choking or turning blue while feeding or spitting up
High-pitched cry with arching, stiffness, or limpness

Call your pediatrician right away if

Rectal temperature of 100.4F (38C) or higher in a baby under 3 months: call your pediatrician immediately or go to the ER, this needs to be seen right away. Do not give fever medicine before your baby is evaluated
Low temperature: rectal under about 97.7F (36.4C), or baby is cold, mottled, or hard to warm
Yellow skin or eyes, especially on day 1, or yellowing that spreads to the belly, arms, or legs, or yellowing with sleepiness and poor feeding: call your pediatrician the same day
Forceful or projectile vomiting, green or yellow (bile) vomit, or blood in spit-up or vomit
Fewer than 6 wet diapers a day after day 5
Hard to wake for feeds or refuses several feeds in a row
No wet diaper in 6 or more hours, dry mouth, or sunken soft spot
Unusually sleepy or hard to rouse, very dark urine, or no tears when crying
Not back to birth weight by 2 weeks, or losing weight
Grunting with each breath, nostril flaring, chest or rib retractions, or fast breathing

Every baby is different. These are starting points, not targets to hit. Feed on demand, follow your baby's cues, and let your pediatrician's weight checks be your real answer.
