How Much Does a 1 Month Old Eat

Navigating parenthood is both rewarding and challenging, especially for first-time parents. One question that often arises is, “How much should a 1-month-old eat?” To help put your mind at ease, this guide dives into all you need to know about feeding your one-month-old baby.

Breastfeeding Versus Formula Feeding

Breastfeeding Guidelines

Breast milk is a complete source of nutrition for infants. For the first month, the baby will likely nurse around 8-12 times per day. A nursing session can last anywhere from 15 to 45 minutes.

Formula Feeding Guidelines

Formula-fed babies generally require fewer feedings—about 6-8 bottles per day. Each bottle can contain about 2-4 ounces of formula.

Signs of Hunger

  1. Rooting Reflex: The baby may turn their head and open their mouth.
  2. Crying: Although it’s a late sign of hunger, crying is an obvious signal.
  3. Sucking Movements: Watch for hand-to-mouth or finger-sucking movements.

How to Know If Baby is Getting Enough

Weight Gain

A consistent weight gain is generally the most reliable indicator.

Diaper Output

Expect around 5-10 wet diapers and at least 1-2 bowel movements per day.


An adequately fed baby will be alert during waking hours and satisfied after feedings.

Common Concerns and Solutions


Inconsistent weight gain, fewer wet diapers, and lethargy can indicate underfeeding.


Watch out for spit-ups, gas, and general fussiness as signs of overfeeding.


Contrary to popular belief, feeding on demand, rather than on a strict schedule, is generally more beneficial for newborns.

Expert Tips and Recommendations

  1. No Water or Juice: Babies should not consume water, juice, or other liquids unless specifically recommended by a healthcare provider.
  2. Burping: Make sure to burp your baby after every feeding to release trapped air.
  3. Night Feedings: Expect several feedings during the night as newborns have small stomachs and fast metabolisms.


How can I increase my milk supply?

Breast milk supply usually adjusts to demand. Frequent feeding and pumping can help increase supply.

Can I introduce solid food?

Solid food should generally not be introduced until the baby is at least 4-6 months old.

Is it okay to mix breastfeeding and formula feeding?

Yes, many parents successfully do a combination of both, but consult a healthcare provider for personalized advice.


Feeding your 1-month-old involves understanding their hunger cues, monitoring for signs they’re getting enough nourishment, and knowing how to handle common concerns like underfeeding or overfeeding. Whether you choose to breastfeed, formula feed, or do a combination of both, the key is to be attentive and flexible to your baby’s needs. Always consult a healthcare provider for the most personalized advice.
