Pumping and getting out

Sara

So my husband will be taking our big kids to the theme park, it’s about two hours away. We bought passes for 15 months right before finding out I was pregnant so didn’t use them lots and only have a few months left on them. I want to go for the ride and to walk around with baby in stroller for fresh air...but I’m exclusively pumping. How do ppl get out while pumping? I’m sad to miss seeing the older kids have fun. I can’t see buying battery pack for my spectra and sitting in restroom time pump every few hrs and bring cooler on day trip just for breast milk I may be stopping in another month or so, don’t want to invest in freemie or something. Am I just left out of everything that involves leaving home for over three hours? 😭
