If you’ve decided to feed your baby breast milk, it may not always be feasible to feed him directly from the breast. This is where the bottle comes in handy. Whether the breast milk was frozen in the freezer or chilled in the refrigerator, warm it up to make it more appealing to the baby and so that the cold temperature isn’t a shock to his little body. Properly warming a bottle of breast milk is important to ensure that the temperature isn’t too hot when the baby begins feeding.

Step 1

Take the breast milk out of the freezer if it’s frozen. Leave it in the refrigerator for about 12 hours to thaw. Do not thaw breast milk at room temperature.

Step 2

Place the bottle of breast milk upright into a tall cup or bowl. Fill the cup or bowl with warm water so that about three-quarters of the length of the bottle is covered. Avoid letting the water touch the nipple part of the bottle, which may cause contamination.

Step 3

Leave the bottle in the warm water for about five minutes. Take the bottle out and swirl it around gently.

Step 4

Squeeze a few drops of the milk onto your wrist to check the temperature. The milk should be just barely warm. If it’s still cold, hold the bottle under warm running water for another minute or two, testing the temperature every 30 seconds or so, until the milk is warm.
