Feeding Your Newborn: What's Normal in the First Weeks

In one minute

• Breastfed newborns typically feed 8–12 times a day; formula-fed babies, roughly every 3–4 hours.
• Follow hunger cues — rooting, hands to mouth, fussing — rather than the clock.
• Wet diapers, stools, and steady weight gain tell you more than counting minutes does.
• Sudden clingy, extra-hungry stretches around weeks 1–3, 6–8, and 3 months are usually growth spurts rather than a supply problem — check diapers and weight gain, and see the signs below if you're unsure.
• Babies under 6 months need no water at all — breast milk or formula covers all their fluid needs, even in hot weather.

How often should baby eat?

In the newborn weeks, on demand really does mean demand — most breastfed babies want to eat 8 to 12 times in 24 hours, sometimes clustering several feeds close together in the evening. By 6–8 weeks that often eases to 7–9 feeds a day, and by 3 months, 6–8. Formula-fed babies tend to space out a bit more naturally, around every 3–4 hours. There's no universal right gap between feeds — baby's cues are the schedule.

Signs your baby is getting enough

Numbers you can actually check: by day 5, look for 5–6+ wet diapers and 4 or more stools a day, and listen for audible swallowing during feeds. Baby should look loose and relaxed afterward — unclenched fists, calm body. Weight is the real gold standard: most babies dip 5–10% below birth weight in the first days, then regain it by 10–14 days and go on to gain roughly an ounce a day after that.

Growth spurts (and other normal wobbles)

If baby suddenly wants to eat constantly around 1–3 weeks, 6–8 weeks, or 3 months, that's very likely a growth spurt, not a sign that your supply has dried up. Frequent nursing during these stretches is what tells your body to make more milk — it's temporary and it works. And if breastfeeding doesn't come easily at first, that's common too: it's a learned skill for both of you, and most early problems resolve with a bit of support. One more thing worth a note on the fridge: breastfed babies need a daily vitamin D supplement (the AAP recommends 400 IU) starting in the first few days of life — confirm the exact product and amount with your pediatrician, since breast milk alone usually doesn't provide enough. And one more, on hydration: babies under 6 months don't need plain water — breast milk or formula provides all the fluid they need, and extra water can dangerously dilute the salts in their blood, so check with your pediatrician before giving anything else, including in hot weather.

When to call your pediatrician: fewer than 2 wet diapers by day 2, no stool by day 2, continued weight loss past day 7–10, a baby who's too sleepy to wake for feeds, or any fever (100.4°F/38°C or higher) in a baby under 3 months.
