Is My New Baby Eating Enough?

No matter how prepared you think you are, you’ll still have questions once your newborn arrives. One of the most common worries new parents have? Whether their little one is eating the right amount.

Every baby is unique, but there are some basic guidelines to keep in mind when it’s time for a feeding.

Newborn to 2 months: During their first month, babies need to eat 8-12 times each day. That’s about once every 2-3 hours. Some who are breastfeeding, though, can eat every 30 to 90 minutes, and up to 15 times a day. If your baby isn’t waking up on their own for a feeding during the first few weeks, you should get them up to eat on schedule.

If you’re breastfeeding, your little one will spend about 10 to 20 minutes on your breast. Some may nurse for longer, but make sure they are actually sucking and swallowing the whole time.

Giving formula? Plan on your baby drinking 1.5 to 3 ounces at each feeding.

After about a month, they’ll start eating at least 2 ounces at each feeding. As breastfed babies get the hang of nursing, they’ll get more milk from you, too. You may not notice, though, since they’ll do it in less time.

Whether you’re nursing or bottle feeding, as your baby keeps growing, so will their appetite.

At 2 months, they may drink 4-5 ounces at each feeding, 3-4 hours apart.

At 4 months, they may need up to 6 ounces every time. The pediatrician may encourage you to start to introduce solid foods - or advise you to wait if you are still exclusively breastfeeding.

By 6 months, some babies drink as much as 8 ounces of breastmilk or formula even as they go longer between feedings.

Remember: The exact amount your little one drinks will vary from day to day. For instance, they may want to eat more than normal when they are going through a growth spurt. Trust your baby to know how much food they need.

You can watch for a few signs that they are full:

  • They pull away from your breast or their bottle
  • They fall asleep during a feeding
  • They shake their head or keep their mouth closed

Those signs can also help you know that you’re not overfeeding your little one. And at regular checkups, your pediatrician will let you know if your baby’s growth (height and weight) is on track.

When they are getting the right amount of food, you’ll see:

Plenty of wet diapers. The first few days after birth, they may only wet one or two diapers each day. After that, they should need six to eight cloth (five or six disposable) diaper changes every 24 hours, plus have two to five poopy ones each day.

Steady weight gain. After the first 2 weeks, your baby should gain about 4-7 ounces per week until their sixth month, and 3-5 ounces from 6 to 18 months.

Your baby is active and happy. A child that’s eating well will look alert and be active. They’ll also seem content between feedings.

Reasons to call your doctor include:

  • Dark pee 
  • They would rather sleep than eat
  • They won’t latch onto your breast, or they pull away from you
  • They are fussy right after feedings
  • They wet fewer diapers

As a new parent, it’s key to learn to trust your instincts. If you have any concerns about your baby’s eating, check in with their doctor.
