Going back to work can carry every feeling at once: relief, guilt, dread, and missing your baby before you have even left. All of it can be true together. A plan helps, and so does knowing your rights.
Federal law (the PUMP Act) requires most employers to give you reasonable break time and a private space that is not a bathroom to pump, for up to one year after birth. Talk with your employer before you return so the logistics are settled in writing.
Practice with your pump before your first day, build a small stash of milk (a few days is plenty, not a freezer full), and introduce a bottle once breastfeeding is going well so baby is used to it. Plan when and where you will pump during the day.
Whether it is a center, a home provider, or family, start looking early since good spots fill up. Visit, ask questions, and trust how a place feels. Babies often adjust faster than parents expect.
Follow safe storage for pumped milk: clean hands and parts, label with the date, refrigerate or freeze promptly, and use older milk first. If pumping causes pain, redness, or you feel feverish, call your doctor or a lactation consultant.
If feeding logistics are the worry, the feeding page has the storage and pumping basics. If it is the goodbye that sits heavy, that part is real too, and worth tending to, not pushing past.
