Sterilize baby bottles in Instant Pot 4

If you have an Instant Pot (or some other electric pressure cooker), you can easily sterilize items in it safely and quickly.

My two children are not babies anymore, so I don’t sterilize bottles and rubber teats or anything like that, but I sterilize their beakers, straws, and cups.

To start, you will need your metal rack (trivet) that goes inside the inner pot, or if you have a steam basket, you can even use one of those.

You use the metal rack, put the steam basket on top, and then place the items you wish to sterilize inside.

You can fill it up to the top; as long as you can close the lid, it will be fine. Before you place any of the items in, make sure to put between 1 to 2 cups of water in the pot.

There is no exact amount; it doesn’t matter because you’re going to be using steam to sterilize; make sure nothing touches the bottom; that’s why placing the steam rack in the inner pot is essential.

  1. Place trivet/steamer basket inside the inner pot
  2. Add one cup of water to the inner pot.
  3. Load items into the pot (as much as you like, as long as you can close the lid properly)
  4. Close your lid and make sure the seal is closed so no steam escapes.
  5. Press the steam button and set the time to 2 minutes (you can also do 3 minutes if you want)
  6. When the 2 minutes are up, allow the steam to release naturally (natural release). Naturally release for about 4 minutes, then quick release the rest. If you leave it and let it sit until it’s entirely naturally released, that is not a problem.
  7. Remove the lid and carefully remove the items.
  8. Dry the items by air-drying them. No matter how clean your cloth may seem, you risk adding bacteria to the bottles/items. 

Due to the capacity of the Instant Pot, it is perfect for sterilizing large amounts of items quickly.

I hope you have found this helpful, and if you have an Instant Pot or any other electric pressure cooker, why not give this a try and sterilize a few things.

If you are a mom with babies (and maybe you are pumping milk), you will know how much sterilizing there is to do. Using the Instant Pot is a quick and great way to get all that sterilizing done.

You can use either the sterilize function on newer Instant Pot models or pressure cook/steam to sterilize any household glass, silicone, and dishwasher safe plastics on models without the sterilizing function.

To sterilize your baby's bottles in an Instant Pot:

  1. Fill the bottom cooking pot of the Instant Pot with water.
  2. Place a trivet on top of that and add the baby's bottles to it.
  3. Lock and seal the lid, set to steam for 2 minutes, then let sit and release pressure before opening up.
  4. Use tongs whenever removing anything from the inner pot to keep them as clean as you can.

Sterilizing baby feeding bottles is the first line of defense against bugs, germs, and bacteria. Unfortunately, a baby's immune system is not fully developed, so they are susceptible to vomiting and diarrhea.

You need to sterilize baby bottles until they are one year old.

It depends on what method you use, but baby bottles and teats can be sterilized in as little as 5 minutes using a microwave, pressure cooker, or electric steam sterilizer. If using boiling water, they should be immersed for 10 minutes.

Yes, you can. You'll need to make sure that bottles, teats, and other baby feeding items are submerged in boiling water for at least 10 minutes. Regular use of this method may affect some items and necessitate their replacement more frequently.

No. Any remaining water inside the baby bottles will be sterile. However, using a towel to dry baby bottles can reintroduce bacteria into the bottle even if it seems clean.

Using a dishwasher to clean baby bottles is not advised because some models do not get hot enough to kill bacteria and the risk of contamination. However, you can use a dishwasher to wash your child's feeding items before sterilization effectively.

It's recommended that anything coming in contact with a baby and their milk needs to be sterilized. Bottles, teats, breast pumps after every use, and some toys can all be safely sterilized. Soothers and teethers should also be sanitized regularly.
