If you're planning on breastfeeding, it's a good idea to bring your own breast pump to the hospital. This way, you can start pumping right away and get your milk supply going. Plus, it's one less thing for you to worry about while you're in the hospital.
If you don't have a breast pump, or can't bring your own for some reason, don't worry – the hospital will likely have one that you can use. Just be sure to ask a lactation consultant or nurse for help getting started.
