If we’re walking to the beach, we use our everyday stroller that has a big storage basket underneath to wheel most of our beach baby essentials.
As I mentioned above, we just use our everyday stroller when we’re walking from our house (once we get to the beach we carry it to our spot because it’s not great for your stroller to be in a lot of sand with the salt if it’s not meant to be).
We have this collapsible wagon to help us wheel whatever we need when the time comes that we need to bring more toys and entertainment for the baby.
A wet pouch with diapers and wipes (and another empty wet bag for bathing suit, etc.), burp cloths (an extra goes in the cooler to wipe her down if it’s hot) and a bunch of toys that are easy to wash the sand off of like these stacking cups or this rattle.
