How do I know she's getting enough milk?

Breast, bottle or a little of both, the signs are the same: happy feeds, full diapers and a baby who grows. Here's what to look for.

A mother feeding her baby in a sunlit armchair

She's tucked against you, eyes half closed, one tiny hand resting on your skin, and you can hear her swallow. It's one of the most peaceful feelings there is. And then, a little later, the question every new mom asks: is she getting enough?

Here's the good news. Your baby is wonderfully good at telling you. Whether you're breastfeeding, formula feeding or doing a combination, you don't have to guess. You just need to know what to watch.

How often newborns eat

Newborns eat often, because their tummies are tiny. Breastfed newborns usually nurse 8 to 12 times in 24 hours, often about every 2 hours. Formula-fed newborns usually eat every 2 to 3 hours, about 8 to 12 times a day.

If you're using formula, the amounts start small. In the first day or two, she may take only about half an ounce at a feeding, then usually 1 to 2 ounces. By the end of the first month, many babies take 3 or 4 ounces at a time, about every 3 to 4 hours.

In these early weeks, don't let her go too long between feeds. A sleepy newborn may need a gentle wake up to eat: try a diaper change, undressing her or stroking her skin. If you're breastfeeding and she sleeps more than 4 hours at night, wake her to nurse.

Reading her cues

She'll show you she's hungry before she ever cries. Watch for:

Crying is a late sign of hunger, so feeding at the first cues usually goes more smoothly. When she's had enough, she'll close her mouth, turn her head away and relax her hands. Many babies seem content and drowsy after a good feed.

Count the diapers

What goes in comes out, and diapers are one of the clearest signs you have. A quick note on your phone after each change makes it easy.

Weight tells the story

It's normal for a newborn to lose some weight in her first few days. A breastfed baby may lose up to 8 to 10 percent of her birth weight before she starts gaining again. That's expected, and it's why her first checkup comes so soon after you go home.

By about two weeks, she should be back to her birth weight, and then she'll keep growing steadily along her growth curve. Her pediatrician will weigh her at each visit, and weighing her is the most precise way to know how feeding is going.

The one thing to remember

Happy feeds, plenty of wet and dirty diapers, and steady weight gain. When you see all three, she's getting what she needs.

Help is part of the plan

Feeding is a skill you're learning together, and nearly every mom has questions. If breastfeeding hurts, if her latch doesn't feel right, or if you're wondering about your supply, a lactation consultant (IBCLC) can watch a feed and help in person. Your pediatrician can help, too, with breast, bottle and everything in between.

Asking early is a sign of a mom who's paying attention. It's never a sign that anything is wrong with you.

When to call her pediatrician

Call her doctor if you notice any of these:

A full, sleepy baby

One day soon you'll notice it: the heavy little body, the milky smile, the arms flopped wide in a deep, happy sleep. That's what enough looks like.

You're feeding her beautifully, Mama, one sip at a time.
