There are many varieties of bottle nipples, so new parents are often surprised.

In addition, according to your baby’s age and desired level of milk flow, there are several “levels” of nipples.

This guide to baby bottle nipple levels will help you figure out when to size up or down.

What Size Nipple for Newborn?

According to the flow rate (how quickly your baby can get milk), the level of your baby’s nibble varies.

Baby’s nipples need a slower flow since you take inconsiderable amounts in at once.

“Level one” nipples mimic breastfeeding since similar muscles are required.

In addition, babies’ nipples typically flow faster as they grow since they drink more milk faster.

In general, napping levels correlate with age, but every child is different.

For example, a newborn may benefit from a faster passage of milk (especially if they eat aggressively), and an older baby may enjoy a slower progression of milk. 

When choosing a baby bottle, you have many options, including nibble size.

Your baby will feed more comfortably and enjoy feeding more if you choose the right nipple size.

Baby bottles that are smaller (4 fl oz or less) are helpful for young babies. As the baby grows, replace these with larger bottles.

Make sure that your current diaper bag will fit the giant bottle when you choose one.

1. What Are the Benefits of Choosing the Right Nipple Size?

You should make breastfeeding, bottle-feeding, or both a comfortable experience for your baby.

Breastfeeding ensures that your body understands your growing baby’s demand for milk and increases supply, but bottle feeding does not guarantee the same results. 

Over time, bottle nips wear out, and as the baby grows, their needs also evolve.

The flow rate in the nipple will slow down as the baby grows, so they won’t be able to enjoy their milk at a pace that’s comfortable for him.

During feeding sessions, you will see the baby appearing frustrated every time, causing the situation to become more stressful.

In addition, it is more difficult for an infant with slower nips to consume milk, becoming more irritable and crying more often.

2. A Baby’s Feeding Bottle Should Be Changed as They Grow

Although parents use age to determine whether to increase their baby’s feeding bottle size, this is not the most critical factor in changing the size of the nipple.

It is quite easy to determine when a baby is ready to move to a new dimension when you inspect them. Here are some signs:

  • Collapsing the nipples,
  • Babies push away bottles
  • Baby getting frustrated

3. Capacity of The Bottle Nipple

  • Up to six months old, infants have nipples of size one.
  • Nipples in sizes two, three, and four have a giant hole and are perfect for older babies.
  • Once the bottle is turned upside down, a few drops of milk should drip out of the bottle’s nipple before it stops. You might consider a nipple with a smaller hole if your baby’s milk is flowing too quickly. On the other hand, try using a nipple that has a giant hole if your baby seems frustrated by sucking too hard.


By now, you know about the question of what size nipple for newborn?

Although a slower-flowing nipple may be more appropriate for some breastfed babies, most should not have to move up in nipple size.

If your baby can nurse within five to ten minutes and you have a fast flow, they may have trouble finishing bottles that take 30-45 minutes.

The height and shape of standard nipples resemble the condition of your breast, while other types resemble your nipples. 

Frequently Asked Questions (FAQs)

Is there an ideal time to increase my baby’s nipple size?

A baby’s nipple level can be changed at any time.

It may be enough for some babies to stay at Level 1 through their feeding days, while more aggressive eaters may advance more quickly than expected.

You’ll know it’s time to move up a level when the flow is too slow.

How big of a nipple is appropriate for a three-week-old?

Unless your baby is an extremely preemie who may need more time and cannot handle the flow, you can begin with a newborn nipple.

The length one is expected on newborn nipples.

How does a nostril flow that is too fast cause gas?

Your baby might suck in a lot of air with formula if they’ve outgrown their nipple size.

Extra air also increases your baby’s risk of having gas (and gas pains.)

If she is going through her nipples too quickly, she might swallow too much formula, which can also cause gas.
