It’s one thing to be free to pump at the hotel as you pack your souvenirs, but it’s a whole other treat to be pumping as you and the family hit the amusement park. As long as you have a compatible pump to fit the Freemie system, you’re good to go — and there are quite a few pumps from popular companies that they’re compatible with. The pump pictured here, the Freedom, needs to be plugged in but the Equality pump uses hand-pull action. No matter which pump you end up going with, the win here is that you can pull the milk and store it all with your shirt still on. Slip the cups in and fill ’em up!
