Okay kiddo, imagine you're going to a party and your mom told you that some of the food and drinks won't be marked with a special sticker. This sticker is called a "kosher certification" and it's like a special seal of approval that means the food meets certain religious standards. However, not all foods need this special sticker to be considered okay to eat at the party. It's like if you wanted to eat an apple instead of a cookie - you don't need anyone to tell you which one is better for you, you can decide for yourself. Same thing goes for food without the kosher certification - you can still eat it if you want, but you may want to ask someone if it meets your own personal standards.
