How Much Should Baby Eat – How Can I Tell If My Baby Needs To Be Fed?
Do not wait for your baby to start crying to begin feeding.
Crying is a late sign of hunger.
However, babies’ cries are not always a sign they need to be fed.
Other ways to tell if your baby needs to be fed [2]:
- Opening their mouth
- Sticking out their tongue
- Moving their head from side to side
- Sucking on their hands, fingers or fists
- Puckering their lips as if suckling
- Nuzzling at mom’s breast
- Exhibiting the rooting reflex (moving their mouth in the direction of something that is stroking or touching their cheek)

How Much Should Baby Eat – How Much Is Enough?
Every baby is different, but there are statistics that provide loose guidelines.
Below are the averages of how much food babies should be consuming [1][3]:
- Newborns: 1.5 – 3 ounces (45-90 milliliters) every 2-3 hours
- 2 months: 4 – 5 ounces (120-150 milliliters) every 3-4 hours
- 4 months: 4 – 6 ounces (120-180 milliliters), frequency dependent on size
- 6 months: 6 – 8 ounces (180-230 milliliters) every 4-5 hours dependent on baby food is being introduced

How Much Should Baby Eat – Look For Growth Spurts
As babies mature, they should eat more and go longer between feedings.
There may be times when your baby is hungrier than usual which may mean a growth spurt!
Growth spurts generally happen around the ages of:
- 7 – 14 days old
- 3 – 6 months
- 4 months
- 6 months

How Much Should Baby Eat – Check Your Baby’s Diapers
Make sure that your baby is well hydrated by checking their diaper.
Newborns typically have at least six wet diapers and four bowel movements a day.
A newborn’s bowel movements are thick and tarry.
They become more yellow or green as they grow.
Formula-fed babies have firmer, less seedy stools when compared to breastfed babies.
Their urine should look clear or very pale.
If crystals are present, contact a medical health professional. That may be a sign your baby is dehydrated.
Other symptoms of underfeeding may include:
- Not gaining enough weight
- Discontentment even after feeding is complete

How Much Should Baby Eat – Well-Baby Checks
Always attend checkups with your doctor.
Typically they take place at:
- 2 weeks
- 2 months
- 4 months
- 6 months
- 9 months
- 12 months
- 15 months
- 18 months
- 2 years
During well visits, your baby is weighed, and length (height) is measured.
Your baby undergoes a thorough physical assessment.
Many times, this is when subtle anomalies are caught. Your doctor will ask you what activities and behaviors your child is exhibiting.
This will help determine if your baby is meeting typical developmental milestones.
Well-child visits are an excellent time to ask questions and learn what to expect.
