I like peanut butter, but I don't eat it very often. DD17 is deathly allergic to peanuts and tree nuts, so it's not something I like to keep around. When I do have it, I have to be really careful about clean up. She's only consumption allergic, but I'm always afraid that I'll leave some residue on a counter that she'll touch and then unknowingly put her finger in her mouth if she's in a nervous nail-biting phase.
As for brands, I couldn't care less. I also prefer chunky over creamy. My parents were just in town and my dad is a big peanut butter on toast fan. They left behind an unopened jar of Peter Pan natural creamy. I'm eating it, just because a spoonful is a good little snack if my tummy rumbles between meals. I honestly don't see much of a difference between the cheaper store brand.
Side note- hardly healthy, but my favorite thing...a bag of milk chocolate chips and a jar of peanut butter. There's nothing like a spoonful of chips and peanut butter...it's better than any commercially produced peanut butter cup.
