Yep, technically you can use whatever pump you like. When you’re pumping for long sessions though, you might tire out with a manual breast pump. Sure, they’re great for travel, but manual pumps can exhaust your hands.
When it comes to power-pumping, many moms prefer to go with an electric double pump. That way, you have your hands free and can rest both breasts during the break.
All of that said, the bottom line is to use the pump that you prefer. If you are comfortable and getting milk, stick with it!
