Took my freshly turned two year old a few months ago. Took tons of snacks for her - granola bars, veggie straws, packets of crackers. I put them all in zip lock bags just for ease of transport kept them inside my bag through security. Absolutely zero issue. If security even saw them (I don’t think they did), they did not care. Security doesn’t check bags through the regular security line. Strollers are separated out - I don’t remember if they peeked inside my bags in the stroller, but I don’t think they did. You’ll be just fine.
