Does Baby Bottle Size Matter?

Once you determine which brand of baby bottle you want to use, you have to decide which size you want. Does size matter when it comes to formula?

If you are breastfeeding and need to express milk for your baby's caregiver when you return to work, you need to think about bottle size. If your baby comes home from the hospital and you do not have any more ready-to-serve bottles that have the nipple screw on top of the container, you need to think about bottle size. There will always be pros and cons for any decision, and baby bottle size is one of those decisions you make for your baby.

Four-Ounce Bottle

Pros:

  • Your baby only drinks 2 to 4 ounces of milk each feeding for the first few months.
  • As your baby gets older, it is the perfect size for your baby to hold up on their own.
  • Smaller bottles cost less than bigger bottles
  • If your baby needs an extra ounce or two after a feeding, it is easy to have on hand
  • You can fit more bottles in a diaper bag or cooler bag

Cons:

  • By the time your baby starts to drink 5+ ounces at a time, you have outgrown the four-ounce container or have to make multiple bottles.
  • More smaller bottles = more time washing bottles

Eight-Ounce (or Larger) Bottle

Pros:

  • Ideal for older babies who take more than five ounces of milk at a time
  • Good storage when you are pumping breast milk and need a container
  • Holds enough milk, even if your baby may or may not want an extra ounce

Cons:

  • Too big for all feedings, especially during the early months
  • Your baby may not be able to hold it when they want to (doesn't balance as well, too heavy, etc.)
  • Takes more room in the diaper bag

Whether you choose four-ounce bottles, eight-ounce bottles, or a combination of both, have enough for your needs so that you are not washing last minute when your little one is hungry. If you are supplementing your breastfeeding, have at least four on hand for your caregiver. If you are exclusively formula-feeding, consider up to 12 bottles to cover all of your feedings during the day and a few extra when your little one wants more during a growth spurt.
