After unsuccessfully trying to breastfeed our newborn twins, we quickly moved to bottle feeding. At first my wife pumped and we filled bottles with breast milk. After several weeks of this, we switched to formula feeding.
Finding the right formula
There are three types of baby formula: ready to use, powdered, and concentrate. We preferred the powdered kind because you didn’t need to refrigerate it after it was opened.
When you get free or cheap formula direct from the manufacturer, you can’t always pick what type of formula you want.
You’ll need to experiment with which brand of formula works best for your twins. We had success with bulk formula from Costco since it was cost effective, and our girls consumed it just fine.
How Many Bottles
Your twins will go through between 6 and 8 bottles per day per baby. You can stock that many bottles in your home or just be prepared to wash them throughout the day.
You’ll typically find different types of bottles for your twins at the store.
Bottles come in various sizes like 4 oz, 8o z, 9 oz, 11 oz, etc. If you want to save money, buy a larger size. You’ll need it eventually, and you can still use it for newborns with the right nipple and without filling it up all the way.
Make sure you don’t give your babies scalding hot formula or milk to drink.
The microwave is notorious for unevenly heating liquids and can give your baby an unpleasant surprise.
When we had to reheat breast milk that was stored in the freezer, we’d warm a large cup of water in the microwave, then take that out and let the bag of milk sit in the water for a few minutes to warm up. This gave us a more even warming without any super-hot surprises.

For formula, we kept a pitcher of water on the counter at room temperature that we used for mixing up the formula. Room temperature water worked great and our girls did fine with it.
Preparing the Bottles
You’ll get so good at preparing bottles that you’ll be able to hold one baby with one arm and make a bottle with the other.
If we were thinking ahead, we’d pre-fill powdered formula in the bottles at the beginning of the day or before bed (to make nighttime feedings easier).
When it came time to feed, we just added the right amount of water, screwed on the nipple, swirled or gave it a good shake, and then sat down to feed the twins.
