Baby Food Ages 🙄

So I’m at a loss with baby food suggested ages and I’m wondering if someone can shed some light on it for me.

My boy loves the squeeze pouches of fruits and veggies, but he mostly eats whatever we’re eating. Why are there some pouches for 12 months+, toddlers, children, etc, when he’s eating everything that we eat minus a few things? I look at the ingredients and they’re still just like, purees sugar, no new additives, so why do I have to buy these expensive baby pouches when he eats all the ingredients in the cheap children’s pouches!?
