The short answer
Freshly pumped milk keeps up to 4 hours at room temperature, 4 days in the fridge, and about 6 months in the freezer, with up to 12 months acceptable. Most employees have a federal right to pump at work for a year after birth, in a private space that is not a bathroom.

How often to pump
If pumping replaces feeds, aim to pump about as often as your baby would eat. In the early weeks that is 8 to 12 times in 24 hours. A lactation provider can help you build a schedule that fits your day.
How long breast milk keeps
Room temperature (77°F or colder): up to 4 hours
Refrigerator: up to 4 days
Freezer: about 6 months is best, up to 12 months is acceptable
Thawed in the fridge: use within 24 hours, and do not refreeze
Leftover milk after a feed: use within 2 hours
Pumping at work
Most employees can take reasonable breaks to pump for one year after birth.
The space must be private and cannot be a bathroom.
Breaks can be unpaid if you are fully off duty, but any work you do while pumping must be paid.

Chat with Phia’s providers is included in the $19 a month membership. Some Pennsylvania Medicaid plans cover Phia when Phia has a contract with the plan, and covered members typically pay nothing. Phia works alongside your OB and your baby’s pediatrician. It does not replace them, and in-person visits are not included.
