How Long Can a Two-Month-Old Baby Go Without Feeding?

How long can a two-month-old baby go without drinking milk?

Hello Dr.
Hsiao, my baby just turned two months old.
Now, before bedtime at 9 PM, he drinks 150 ml of milk and can sleep until around 2 or 3 AM.
He wakes up by himself, plays a bit in the crib, and then goes back to sleep.
If I pick him up to feed him and he doesn't drink more than 100 ml, he falls asleep.
I would like to ask if it's okay not to feed him if he doesn't cry.
What is the longest duration a baby can go without feeding? Thank you.

As long as the infant's height and weight are increasing appropriately, and they urinate more than six times a day without the urine being yellow or concentrated, it indicates that the milk supply is sufficient and the baby is not dehydrated.
Therefore, there is no need to force the baby to drink milk while they are asleep; when they wake up after a longer sleep, they will likely drink more to compensate.

When it comes to feeding a two-month-old baby, it's essential to understand that infants have unique nutritional needs that can vary significantly from one child to another. Generally, a two-month-old baby can go without feeding for a period of time, especially if they are gaining weight appropriately and showing no signs of dehydration.
According to pediatric guidelines, a baby of this age typically needs to be fed every 2 to 4 hours, but this can vary based on individual circumstances. If your baby is sleeping for longer stretches, such as from 9 PM to 2 or 3 AM, and is not showing signs of hunger (like crying or fussing), it is generally acceptable to let them sleep without waking them for a feeding. The key indicators that your baby is getting enough nutrition include consistent weight gain, adequate wet diapers (at least six per day), and a healthy appearance (not dehydrated or lethargic).

In your case, if your baby is drinking 150 ml before bed and then sleeping for several hours, it suggests they are likely getting enough nourishment. If they wake up and play for a while before going back to sleep, this behavior is also normal for infants. Babies often have periods of wakefulness where they may not necessarily need to feed immediately.
As for how long a two-month-old can go without feeding, it can vary. Some babies may go up to 6 hours without needing to eat, especially during the night. However, it is crucial to monitor their overall health and development. If your baby is consistently sleeping longer and not waking up for feeds, it is advisable to consult with your pediatrician to ensure that this pattern is appropriate for your child's growth and health.

It's also important to note that while some parents may worry about their baby not eating enough during the day, infants have a natural ability to regulate their hunger. If they are hungry, they will typically let you know through crying or fussiness. If your baby is sleeping soundly and not showing signs of hunger, it is usually fine to allow them to continue sleeping.

In summary, as long as your baby is gaining weight appropriately, producing enough wet diapers, and appears healthy, it is generally acceptable for them to go several hours without feeding, especially during the night. Always consult with your pediatrician if you have concerns about your baby's feeding patterns or overall health, as they can provide personalized advice based on your child's specific needs.
