It is one of the first questions every new mom asks, usually at 3 a.m. with a phone timer running. The honest answer: there is no single right number, and your baby is a better guide than the clock.
The short answer
Most newborns nurse somewhere around 10 to 20 minutes per breast. Some efficient babies finish in 5 minutes, and some take closer to 30. What matters more is how often: aim for 8 to 12 feeds in 24 hours, whenever your baby shows hunger cues.
In the first days your baby may want to eat as often as every 1 to 3 hours. Over the first weeks and months, most breastfed babies settle into feeding every 2 to 4 hours, with some cluster feeding and the occasional longer sleep stretch.
One breast or two?
Offer the first breast until your baby slows down, comes off on their own or falls asleep relaxed. Then burp and offer the second side. Some babies take both every time, some take one. Both are normal. Start the next feed on the side you finished on, or the one that feels fuller.
Why feeding length varies
- Milk flow. A fast letdown means a shorter feed.
- Baby’s efficiency. Newborns are learning. Feeds get faster with age.
- Storage capacity. Breasts hold different amounts, and this is not related to size.
- Side differences. Most moms have one breast that makes more.
- Time of day. Milk volume is often higher in the morning, and evening feeds can be longer and closer together.
- Feeding frequency. Babies who eat often may take shorter feeds.
- Growth spurts. Expect a few days of near-constant nursing now and then. This is cluster feeding, and it tells your body to make more milk.
Watch your baby, not the clock
Signs a feed is going well:
- You see deep, slow sucks with pauses, and you can hear or see swallowing
- Baby’s hands start out fisted and relax as the feed goes on
- Baby comes off content or drowsy
- Your breast feels softer afterward
- Feeding is comfortable for you
Signs your baby is getting enough overall:
- At least 6 wet diapers a day after day 5, with regular yellow stools
- Back to birth weight by about 2 weeks, then steady gain
- 8 or more feeds in 24 hours
When to check in with a lactation consultant
- Feeds regularly last longer than 40 to 45 minutes, or baby never seems satisfied
- Feeds are always under 5 minutes in the first weeks and diapers or weight are low
- Baby is too sleepy to wake for feeds, or has fewer than 8 feeds a day
- Nursing hurts, or your nipples are cracked or misshapen after feeds
- You are worried about your supply
Call your pediatrician right away if your newborn has very few wet diapers, dark urine, a sunken soft spot, or is hard to wake.
Frequently asked questions
Is a 5 minute feed enough? It can be, if your baby is swallowing well, has plenty of wet and dirty diapers and is gaining weight.
Should I wake my newborn to feed? In the early weeks, yes, if it has been more than about 3 hours during the day or 4 hours at night, until your baby is back to birth weight and gaining well.
Should I switch sides at a set time? No. Let your baby finish the first side, then offer the second.
My baby wants to nurse every hour in the evening. Is that normal? Yes. Cluster feeding is common and usually passes in a few days.
Do feeds get shorter as babies grow? Usually. By 2 to 3 months many babies finish in 5 to 10 minutes per side.
