One of the first questions new parents have is, “How much should my baby be eating?” It’s a great question! Feeding your baby is one of the most important ways you care for them, and it’s natural to wonder if they’re getting enough. Let’s break down what to expect when it comes to feeding your little one during those first few months of life, whether you’re breastfeeding, formula-feeding, or doing a combination of both.
In the First Few Days: Tiny Tummies
Newborns have very small stomachs, about the size of a cherry on their first day of life. This means they can only handle a little bit of milk at a time. During the first few days:
- Breastfed babies will drink about 1–2 teaspoons of colostrum (your first milk) per feeding. This nutrient-packed milk is just what their tiny tummies need.
- Formula-fed babies will typically take 1/4 ounce to 1 ounce per feeding in the beginning, feeding every 2–3 hours.
Expect to feed your baby 8–12 times a day during these early days. Frequent feeds help establish your milk supply if you’re breastfeeding and ensure your baby stays well-hydrated and nourished.
Weeks 1–4: Building Up
By the end of the first week, your baby’s stomach will grow to the size of a walnut, and they’ll be able to take in a bit more milk.
- Breastfed babies will nurse every 2–3 hours, with feeds lasting 15–20 minutes per side (though this can vary).
- Formula-fed babies will drink about 2–3 ounces per feeding, still eating every 2–4 hours.
Watch for hunger cues like rooting, sucking on their hands, or smacking their lips. Crying is a late sign of hunger, so aim to feed before they get too fussy.
Month 2: Bigger Appetites
By the second month, your baby will be growing quickly, and their feeding needs will increase to support all that development.
- Breastfed babies may still feed every 2–3 hours, though some might start going a little longer between feedings, especially at night.
- Formula-fed babies will likely drink about 4–5 ounces per feeding, eating every 3–4 hours.
Around this time, you might notice your baby going through growth spurts, usually around 6 weeks. During these spurts, they’ll seem hungrier than usual and may want to feed more often for a few days. This is normal and helps them grow!
Month 3: Starting to Settle Into a Routine
By three months, many babies begin to develop a more predictable feeding routine.
- Breastfed babies may feed every 3–4 hours and might cluster feed (several short feedings close together) in the evening.
- Formula-fed babies typically take 5–6 ounces per feeding, about 5–6 times a day.
Your baby is getting better at feeding efficiently, so breastfeeding sessions might become shorter. Watch their cues—babies are great at letting you know when they’re full or need more.
How Do You Know If Your Baby Is Eating Enough?
It’s natural to wonder if your baby is getting enough milk, but there are a few easy ways to tell:
- Plenty of wet and dirty diapers: In the first month, expect at least 6–8 wet diapers and 3–4 dirty diapers per day.
- Steady weight gain: Your pediatrician will monitor this at regular check-ups.
- Contentment after feeds: A well-fed baby will generally seem calm and satisfied after feeding.
- Good energy levels: Your baby will be alert and active during their wake times.
If you’re ever unsure, don’t hesitate to reach out to your pediatrician or lactation consultant for support.
A Few Feeding Tips for the First Few Months
Follow your baby’s lead—babies are great at self-regulating how much they need. Trust their hunger and fullness cues. Growth spurts are normal, so your baby may want to feed more often during these periods. Burping your baby during and after feeds can help reduce gas and fussiness. If you’re breastfeeding, staying hydrated and eating well helps support your milk supply.
Enjoy the Feeding Journey
The first few months with your baby are full of changes, and feeding is no exception. Whether you’re breastfeeding, formula-feeding, or a mix of both, every feed is a chance to connect, nourish, and bond with your little one. Remember, each baby is unique, so don’t stress if your baby’s feeding pattern looks a little different—just focus on their cues and trust your instincts.
You’re doing an amazing job, one feed at a time!
