Enough milk storage containers for the number of pumping sessions during your workday.
Wear easy access clothing that opens in the front.
An extra shirt, sweater, or vest at work in case your milk leaks. Patterned clothing also hides spills and leaks better than plain clothing.
Bring a shawl or small blanket for personal privacy in case others are in the pumping area or if the area you're pumping in is chilly.
A water bottle and nutritious snacks to ensure you meet the calorie needs of breastfeeding.
Any props, such as a pillow, that make pumping more comfortable for you.
Create a "Do Not Disturb" sign to use if you are pumping in your office.
An iPod, book, magazine, or picture of your baby to help you relax so that your milk will release more easily.
Other supplies that you might find helpful, such as antibacterial wipes, scotch tape, a pencil to mark the bottles with the date, and supplies to clean the pump.
