When trying to create your baby registry, or simply explaining to friends and family what you might need to get prepared for your new arrival, baby bottles can leave you many baby bottles DO you need?

Well the answer is going to depends on a few varying factors such as how you plan on feeding your baby being one of the most important ones.

You’ll also want to keep an open mind about the style of bottles that you purchase because if your baby ends up with colic, then you may need to switch all your bottles to a more colic friendly brand.

Regardless of how you choose to feed your baby, you’re going to need to have bottles on hand.

How Many Bottles Do You Need If Your Baby Is Breastfed

If you are going to breastfeed your baby you may be wondering why you would even need baby bottles.

Even the most exclusively breastfeeding mothers end up pumping milk with a hand pump or an electric breast pump and where does that milk go? Into a bottle! If your baby is not hungry and you need to get some milk out of your breasts, then you’re going to need to use that pump.

Saving the breast milk in a bottle and in the fridge or freezer will help you if you need to go outside of the home and cannot feed the baby directly from the breast, or if you want to give Dad a chance to bond and feed the little one.

So how many bottles do you need if you are breastfeeding? At least 5.

Why 5?

Most bottles will be used for the pump and then stored in the fridge. If you’ve used two bottles in one pumping session and put them both in the fridge, it’ll be very helpful to have at least 2-3 more bottles that are waiting to be filled. They also come in handy if you need to leave the house.

How Many Bottles Do You Need If Your Baby Is Formula Fed

Formula-fed babies will need more bottles than breastfed babies. We suggest having at least 8-10 baby bottles ready at home before the baby arrives if you plan on formula feeding.

Babies eat a lot and sometimes go through these growth spurts where they don’t stop eating all day long. What a shame it would be to run out of clean bottles and having a screaming baby demanding to eat. This is why you’ll need a good collection of baby bottles before the baby arrives.

Choosing The Right Bottles For You

Today, there are so many different bottles available in all sorts of sizes, shapes and brands.

You will also find that there are baby bottles that help your baby to not swallow too much air while they feed, which will help with gas when they finish eating.

We love glass bottles for newborns because the mother holds them anyway and there is no chance of the baby breaking the bottle. For toddler we recommend the plastic bottles, just because we know that toddlers like to throw stuff.

You’ll also want to keep the size of the baby bottle in mind. Newborn bottles are normally smaller and can hold 6 ounces of liquid whereas older baby bottles can go up to 12 ounces.

Most baby bottles can be washed in the dishwasher and sterilized in a sterilizer which is very helpful for new parents.

Things To Keep In Mind When Shopping For Baby Bottles


Baby bottles these days come in different materials so it is important to know the difference between them when you are choosing the best baby bottle so you can find the right bottles for you.

Glass: Glass is a BPA free material that is durable and lasts longer than other materials. They do cost a little bit more than the other bottles but they are a lot easier to clean too which is a desirable selling point for many parents. They are easy to sanitize without worrying about melting them either. Babies like the glass bottle because it doesn’t absorb odours like the plastic ones. A lot of glass bottles are also compatible with breast pumps, so you don’t need to go out and purchase different bottles for pumping and for feeding. The not so good things about the glass bottles are the fact that they are more difficult to find. Walmart and target are likely to not carry them, so they should be ordered on Amazon or a specialized baby store. Toddlers tend to throw things around as well, so parents do worry that glass bottles can shatter. While that is a common concern, unless the child is throwing the bottle directly onto concrete, there is little chance of them actually breaking apart. Glass bottles these days are also made from reinforced glass, meaning that if they do shatter, the edges won’t be sharp but rather round, reducing the chance of your child hurting themselves.

Plastic: Plastic bottles are very popular among parents today and are light and shatterproof unlike glass bottles. Many plastic baby bottles are BPA and chemical free so there is little worry about presenting your baby with chemicals in their food. Plastic does wear away more easily than glass and so plastic bottles will need to be replaced regularly. They are less expensive than glass bottles and are readily available in shops that sell baby gear.

Silicone: Silicone bottles are BPA and chemical free also which does make them a desirable type of baby bottle. They are not breakable and very light too. Their drawback is that they can be difficult to track down as not many stores carry them, so you may have to look to Amazon for your favourite bottle if you need to replace one.

Stainless Steel: Stainless steel bottles are newer to the baby market and it is a good material for baby bottles. Stainless steel is not breakable but also light. They don’t contain BPA or other chemicals and are pretty easy to clean. Their main drawback is that they are hard to track down and can get expensive quickly.


Yep, you heard us right, there are some baby bottles that offer disposable options. These bottles are the ones that have drop-in inserts that you can fill up with your milk. when finished, just toss the liner in the garbage and clean the bottle and the nipple properly. This is a single-use option only.

Bottle Shape

All bottles come in different shapes such as tall and thin or short and curvy. Many bottles are designed for babies to be able to hold up their bottles easily on their own. If you are going to be out and about frequently, it’s a good idea to think about your stroller or stroller organizer to ensure that the bottles will fit nicely in the holders.

Anti Gas

Most bottles have the features that you would need to keep your babies gassiness in mind. Bottles that have proper ventilation help prevent colic and gassiness because they have features that prevent them from swallowing too much air.

Nipple Type

Every bottle has a special nipple designed for different purposes. There are orthodontic nipples that help accommodate the infant’s gums as well as bulb nipples that have flat sides that rest on the tongue. When purchasing nipples be sure to look at the flow rate and the recommended age, as some nipples have faster flow than others and are made for toddlers rather than newborns.

Bottle Size

Most baby bottles can be purchased in newborn sizes which are around 4-6 ounces and toddler sizes which go from 8-12 ounces.

If you are purchasing bottles for your newborn and asking yourself how many baby bottles do you need, you’ll want to get a handful of newborn and a handful of larger bottles as well. Go for a 5-5 ratio if you’re planning to formula feed.

Available accessories

Some bottles have feeding accessories such as bottle warmers, bottle totes bags, sterilizers and bottle drying racks. Some parents like to match these items and like to purchase everything as a complete set for their kitchen.

On The Go Bottle Must Haves

These are items you should have in the diaper bag when you’re out with baby if you are using bottles to feed the baby.

Bottles: Pack one or two bottles, depending on how long you’ll be out with the baby. If you know you can wash your baby bottle, then you may only need to bring one.

Nipples: Sometimes baby nipples fall off the bottle when you’re making a new bottle for the baby so it’s a good idea to have a spare one in the bag.

Insulated Carrier: an insulated carrier will keep the baby bottle warm or cool for a few hours which can be very helpful on a hot day.

Formula: Pack enough formula for your baby and use a baby formula dispenser to make the measuring easy while you’re out.

Water: You should always use clean water when making your baby bottle

Burp Cloths

Baby Bottle Safety

Plastic bottles: Plastic bottles are perfectly fine as long as they are labelled BPa free. We want to ensure that our baby isn’t ingesting any sort of chemicals.

Microwave: Plastic bottles should not go into the microwave and some should not go into the dishwasher either as they could melt from the high heat. Some plastic bottles are ok on the top rack, but not all of them are.

Cereal Safety: Some parents like to add baby cereal to the formula in the baby bottle. While this is convenient it can also lead to overfeeding or having cereal stuck within the nipple and you’ll have to go and replace it.

Burping: Each feeding session should end with a burp to avoid gassiness while the baby sleeps. A Baby will; have a hard time sleeping if they have a gas bubble that may be difficult to get out.
