Baby Bottle Size Guide for New Moms


Not sure whether to go for big or small baby bottles? Luckily for you, we have a straightforward baby bottle size guide so you can buy something ASAP.

The bottle’s size is definitely a priority, but you should think about the nipple, too. These two components go hand in hand. If one of them isn’t right for your baby, you would not be able to ensure proper nourishment.

First, let’s focus on the bottle size.

Start with smaller baby bottles

Big bottles for newborns aren’t exactly dangerous, as long as the nipple is safe for a fragile baby. However, you would constantly waste milk since newborns can only consume a limited amount in one sitting.

That’s why you should prepare four-ounce bottles before your due date. Feel free to buy eight- to nine-ounce bottles when your baby reaches four months, according to BabyCenter.

Buy the smallest kind of baby bottle nipples at first

No wonder the smallest size for bottle nipples is typically labeled “stage 1”. You clearly have to choose 1 before anything else. It provides the slowest flow to avoid choking a newborn.

How about older babies with a bigger appetite? Luckily for you, bottle nipples in stores are sorted through age range. There’s no need to worry about choosing the wrong size anymore.

In Conclusion

The baby bottle size guide promotes smaller containers and nipples for newborns. Only switch to bigger plastic or glass options when your child finally has a bigger appetite.
