The ideal size of a baby bottle will depend on a few different factors. Some parents prefer smaller bottles because they are more portable and pose less of a risk of trapped air. These work fine in the early months until you need larger feeds.

This is when it is time to consider the best bigger baby bottle for your child. Do you go for a standard 8oz bottle or is it better to have the larger capacity of something bigger?

Bigger is better for kids with larger appetites so you only need to make one bottle. But, how big do baby bottles get? Are you going to find something large enough for their appetite and can you also do so when pumping breast milk?


Can you get baby bottles bigger than 9 oz?

It is easy to get into a set pattern when using baby bottles. There are the smaller bottles that babies use for the first few months when feeds are smaller, and then the larger bottles that accommodate a growing appetite. The smaller ones are 4oz on average and the larger 8oz. But, what if this isn’t big enough?

Thankfully, there is no need to worry if you are struggling with one of the more standard 8 or 9oz baby bottles with your hungry child. There are plenty of baby bottles out there that have a larger capacity. You might find that you only need to go up a little bit to a 10oz bottle or that you would prefer something that can hold 12oz.

Parents using breast pumps that need to express more than 8oz should also look to see if the company has any bigger bottles that are compatible.


What is the largest baby bottle size?

The most common size for a bigger baby bottle is 8-9oz, but that doesn’t mean that it is the largest out there. There are plenty of brands that provide larger capacity baby bottles for kids that need larger feeds or parents that want something more convenient for their feeding regime.

Some of these alternative bottles aren’t that much bigger at 10oz. This could be fine for your needs. The largest right now seems to be 12oz, with a few companies extending that capacity for larger feeds. There may come a time where bottles that are 13oz or larger are more accessible too.


Can you get larger bottles for pumping?

This is a common concern for parents that pump breast milk and store it for later use. The bottles that come with your breast pump are more than likely going to be standard sizes. Also, a lot of brands have bottles and attachments that only work with products from their range. This can be limiting for parents that have plenty of milk to express.

Companies can’t assume that parents will all express 8oz of milk maximum. Some mothers can go as high as 10-12oz with ease and don’t want to swap out the bottles halfway through. Unfortunately, a lot of the bigger names stick with sets of 5oz and 8oz bottles because it is the norm.

So, it helps to find a brand that has larger sizes available that are also compatible with different devices. Get in contact with them to see if they can help.


Can newborns use bigger bottles?

There are practical advantages to choosing larger baby bottles. The first is that you can make up as much formula as you want in one bottle rather than having to switch bottles halfway. For example, you may have a newborn that takes larger feeds or that needs a little more for weight gain or other health issues.

Is it better to make up 5oz of formula across two 4oz bottles or to put 5oz in one 8oz bottle? The latter is certainly more convenient as you don’t have as much hassle with the preparation and cleaning process. Nor, do you need to stop the feed mid-way and risk upsetting your child.

However, there are also disadvantages to choosing these larger bottles for newborns. For a start, larger bottles are more difficult to handle, especially if your baby wants to grab at the bottle while feeding.

Secondly, there is a great risk of trapped air and bubbles when a bottle isn’t completely full. This can be a bad idea for gassy or colicky babies unless you have a vented bottle or special formula.


At what age should babies use bigger bottles?

Because of those potential downsides in using a bigger bottle for newborns, it is a safer idea to make a switch from a smaller to a bigger bottle part-way through their development.

The common recommendation here is to stick with the smaller 4oz bottles until your child is around 4 months old and then move on to the 8- 9oz bottles. This is when you can decide whether to stick with this size or get one of the larger baby bottle sizes instead.

Just remember that there is no precise time frame here that you need to stick to. You may find that your baby develops a little faster and has an appetite that necessitates a larger bottle at closer to 3 months old.

Or, you may find that they are a little slower to get to this stage and you make the switch closer to 5 months old. Follow your instincts and pay attention to how much your child is eating and their feeding habits.


3 examples of larger baby bottles to consider.

While those larger baby bottles for pumping are hard to come by, there are quite a few larger baby bottles out there for feeding. You can get products with 10, 11, or 12oz capacities for a more convenient feed. You can always start with the 10oz and then go bigger if needed. Here are a few great examples to consider.


1) MAM Easy Active Bottle 11 oz

This first option is one of the 11oz products with more than enough room inside for larger feeds. It would be all too easy to make these larger bottles bulky and hard to use, but this one still has a got ergonomic shape to make it easier to hold. There are two bottles in the pack, so you can have one sterilizing or drying out while the other is in use.

Other sets do have more bottles, however. There are also the benefits of the easy-to-use silicone nipple, the leak-proof cap, and the fact that they are 100% BPS-free. The use of cute unisex designs on the side is another nice touch that makes them more fun to use, but they are random.


2) Avima 12 oz Anti Colic Infant Bottles

These bottles are completely different and show that there are different styles and features even when searching for larger baby bottles. This set is at the higher end of the scale in terms of size at 12oz. There are many similar features such as the nice use of silicone in the soft nipple and the BPA-free plastic for the bottle.

However, this one has a faster flow with a different shape to the neck. This should make it a better choice for babies that suffer from colic, especially as there is a greater risk of air bubbles in these larger products. A bonus feature is that there are very few parts to disassemble and clean, making this a time-saver.


3) Philips Avent Anti-Colic Baby Bottles

This final set is another anti-colic baby bottle but it has a slightly different approach. Here, there is a choice of flow rate depending on the nipples used. This level of personalization can help parents make better choices and soothe babies a lot faster.

The design of those nipples, the anti-colic vents, and the bottle more generally, are pretty good and they are all easy to clean. The capacity is great at 11oz so there should be no problem getting a full feed in one bottle.

The bonus here is that there are four bottles in the pack. This adds great value and convenience for parents as you can have a better rotation system for using, cleaning, and drying the bottles.


Can you use larger baby bottles than the standard models?

To summarize, you don’t have to put up with using those typical 8oz bottles that you get if they are too small to be effective. There is no point making up two smaller feeds and interrupting the moment when you can get something that holds up 10 or even 12oz.

Many of these larger bottles for babies are just as easy to use and have the added benefit of anti-colic features. Also, remember that any guidelines on when to switch to a larger bottle are just for guidance.

You will know when it is time to move on to a bigger bottle if you know it will benefit you and your child. Take a look at some of the best large baby bottles and settle into a better feeding regime.
