Bottle Sizes For Newborns: What's The Right Fit?

The number of bottles a newborn needs depends on several factors, including whether the baby is being breastfed or bottle-fed, and how often the parent can wash and sterilise bottles. If a baby is being exclusively bottle-fed, 8 to 10 bottles are recommended. If a baby is being breastfed, 3 or 4 bottles should be enough. Newborns feed between 10 and 14 times in 24 hours, and small 4- or 5-ounce bottles are recommended for the first few weeks.

Newborns need smaller bottles (4-5oz) as they eat less and more frequently

Newborns have small stomachs and feed little and often, so smaller bottles are more suitable for this period. Newborn babies generally feed between 10 and 14 times in 24 hours, and this reduces as they grow. Newborns eat less than older babies, so smaller bottles of 4-5oz are ideal.

Small bottles are easier for a newborn's little hands to grip, and they are also easier to clean. Newborns eat less in one sitting, so smaller bottles are more practical. You can always buy larger bottles and fill them halfway, but it is nice to have the smaller sizes.

Newborns will need around three to four small bottles per day, and you will need to sterilise them between feeds. If you are breastfeeding, you may only need one or two bottles per day, but if you are bottle-feeding, you will need more.

Newborns eat around two to five ounces at a feeding, so 4-5oz bottles are ideal. You can buy larger bottles and fill them halfway, but smaller bottles are easier for newborns to grip and feed from.

Newborns will need to feed every two to three hours, and this may increase to eight to 14 times a day. They may need to eat more frequently if you are breastfeeding, as breast milk is digested faster than formula.

You can move to larger bottles when your baby is around four months old, and their appetite has increased.

Start with 4-5 bottles and move to 8-9oz bottles at 4 months

When it comes to feeding your newborn, there are a lot of options to consider. You might be breastfeeding, bottle-feeding, or using a combination of both. The number of bottles you'll need depends on these factors, as well as your baby's age and appetite.

If you're planning to breastfeed, you'll likely only need 3 to 4 bottles, especially if you're mostly at home. This will allow you to have a few extra bottles for when you need to leave your baby for a couple of hours or if your partner wants to help with feedings.

On the other hand, if you're exclusively bottle-feeding, you'll need more bottles. It's recommended to have 8 to 10 bottles in total. This takes into account the fact that bottles need to be replaced regularly and that your baby's needs and appetite will change as they grow.

Newborns have small stomachs and feed frequently, so it's best to start with 4-ounce or 5-ounce bottles. These smaller bottles are also easier for your baby to grip. You'll likely need 3 to 4 of these smaller bottles.

As your baby grows, their appetite will increase. Around 4 months of age, you can switch to 8-ounce or 9-ounce bottles. Depending on how long you plan to bottle-feed, you may need 4 to 7 of these larger bottles.

It's important to note that every baby is different, and there is no one-size-fits-all approach to feeding. You may need to adjust the number and size of bottles based on your baby's individual needs and feeding patterns.

If bottle-feeding, you'll need 8-10 bottles; if breastfeeding, 3-4

The number of bottles you need for your newborn depends on whether you're bottle-feeding or breastfeeding. If you're bottle-feeding, you'll need 8-10 bottles; if you're breastfeeding, 3-4 bottles should be enough.

Newborns feed between 10 and 14 times in 24 hours, and feeds become less frequent as they grow. If you're bottle-feeding, you'll be washing and sterilising bottles multiple times a day, so it's a good idea to have a stock of them. If you're breastfeeding, you may express milk and store it in bottles, or you may give your baby formula in a bottle occasionally, so it's still worth having a few bottles to hand.

If you're bottle-feeding, you won't need all 8-10 bottles right away. Babies grow quickly and their appetites change, so you'll need to replace and change bottles and teats as your baby grows and their needs and appetite change. You may also want to buy a few bottles at the beginning to test out different types and find the one your baby prefers.

If you're breastfeeding, your baby may be fussier when it comes to using a bottle, so you may need to try a few more types than if your baby was bottle-fed.

Baby bottles come in two sizes: small (4 or 5 ounces) and large (8 or 9 ounces). For newborn babies, it's best to start with small bottles (4oz) and get 3 or 4 of them. Newborns eat less than older babies, and small bottles are easier for them to grip. After about four months, switch to 8 or 9-ounce bottles. Depending on how long you plan on bottle-feeding for, you may need 4-7 bigger bottles.

If formula feeding, consider how often you'll wash and sterilise bottles

If you're formula feeding, you'll need to wash and sterilise bottles regularly. Newborns feed between 10 and 14 times in 24 hours, so you'll be washing and sterilising bottles a lot!

If you're exclusively formula feeding, you'll likely need around four to six bottles to get you started. This allows for sterilising them between feeds. If you're mostly breastfeeding and only need to give the occasional bottle, you'll only need one bottle.

It's important to wash and sterilise bottles until your baby is 12 months old. This will protect your baby against infections, in particular, diarrhoea and vomiting.

Here's a step-by-step guide to washing and sterilising bottles:

• Clean bottles, teats, and other feeding equipment in hot, soapy water as soon after feeds as possible. Use a clean bottle brush to clean bottles (only use this brush for cleaning bottles) and a small teat brush to clean the inside of teats. You can also turn teats inside out and wash them in hot soapy water.
• Rinse all equipment in clean, cold running water before sterilising.
• Sterilise the feeding equipment using one of the following methods:

• Cold-water sterilising solution: Follow the manufacturer's instructions. Leave the feeding equipment in the solution for at least 30 minutes, changing the solution every 24 hours. Ensure there are no air bubbles trapped in the bottles or teats.
• Steam sterilising (electric steriliser or microwave): Follow the manufacturer's instructions, as there are several types of sterilisers.
• Boiling: Make sure the items you want to sterilise are safe to boil. Boil the feeding equipment in a large pan of water for at least 10 minutes, ensuring it all stays under the surface. Set a timer so you don't forget to turn off the heat. Remember that teats tend to get damaged faster with this method, so check regularly for any tears or cracks.

• After sterilising, it's best to leave bottles and teats in the steriliser or pan until you need them. If you do take them out, put the teats and lids on the bottles immediately.
• Wash and dry your hands before handling sterilised equipment. You can also use sterile tongs.
• Assemble the bottles on a clean, disinfected surface or the upturned lid of the steriliser.

It's important to note that putting feeding equipment in the dishwasher will clean it but does not sterilise it. Additionally, teats tend to get damaged faster in the dishwasher, so it's recommended to wash them separately by hand.

How often you need to wash and sterilise bottles will depend on your baby's feeding schedule and how many bottles you have. It's recommended to sterilise bottles after every feed, and you'll need to sterilise them again if they haven't been used within 24 hours.

Glass bottles are heavier and more expensive but are BPA-free

Glass baby bottles are heavier and more expensive than plastic bottles, but they offer peace of mind when it comes to potential chemical exposure. Glass bottles are free from bisphenol A (BPA), a chemical used in the production of hard plastics that has been linked to various health issues in infants and children. While BPA has been banned from use in baby bottles in the US since 2012, it is still a valid concern when using secondhand plastic bottles or purchasing bottles from overseas. Glass bottles are a safe alternative, as they are BPA-free and won't leach harmful chemicals into your baby's formula or milk.

The weight of glass bottles can be a disadvantage, especially for older babies who are starting to hold their bottles. Additionally, glass bottles are more prone to shattering if dropped, which can be a safety hazard. To mitigate this risk, protective silicone sleeves can be purchased separately to provide a layer of protection and reduce the chances of breakage.

While glass bottles are more expensive upfront, they tend to last longer than plastic bottles. Plastic bottles may warp and break down over time, especially with repeated heating and cooling. Glass bottles, on the other hand, are durable and can withstand higher temperatures without leaching chemicals. They can be boiled for deep cleaning and are generally easier to get a thorough clean.

When choosing between glass and plastic baby bottles, consider your budget, your baby's needs, and the level of convenience you desire. Glass bottles offer the advantage of being BPA-free and long-lasting, but they are heavier and more fragile. Plastic bottles are lightweight and shatter-resistant but may come with potential chemical exposure concerns, especially if not properly cared for. Remember to always follow the manufacturer's instructions for cleaning and maintenance to ensure the safety and longevity of your chosen baby bottles.
