How often should you pump while at work?
Pumping for working moms
At work, you should try pumping every three to four hours for around 15 minutes a session. This may sound like a lot, but it goes back to that concept of supply and demand. Your baby takes in milk every few hours. Pumping that often will ensure that you're able to keep up with their needs.
How many times should I pump in a 8 hour work day?
As a rule of thumb, many breastfeeding mothers try to schedule 2–3 pumping breaks during an 8-hour (plus commute) work day; one of these is typically at lunch time.
