Crackers are not nutritious to begin with. Low sodium crackers though, check out Breton and Sky Flakes. You can always add healthy things to it like nut butters, jellies, and hummus.
I second Breton
Simple mills crackers in Costco
@Ellie surprisingly my son hates all bread and jellies and jams and peanut butter it's so weird
Honestly if you look up videos on making your own crackers it’s super easy
