toddler diaper bag

What do y'all keep in your toddler diaper bags? I've been forgetting the diaper bag in the car for awhile. This weekend we are going on a daycation to the zoo and my diaper packing skills are out the window 😂 here's what I have in it so far

Diapers, wipes, diaper changing pad, snack container, snack bowls for them, sippy cups, first aid kit, sun screen, a few toys, plastic bags and an extra set of clothes.. Anyone else have any other good items to pack that I didn't think of? I have PLENTY of space in the backpack but also have twin toddlers so everything gets doubled. I don't want to pack too heavy.

We have a plastic container in the car for extra things...the diaper bag is for what will need to be carried through the zoo.
