Not even sure what to do

My 10 month old son will eat and eat and eat and won't stop. We can feed him whatever we are eating and he will eat a lot of it but yet still expects bottle after bottle. I'm not even sure what to do at this point. He can eat multiple jars of baby food at once and still want a bottle afterwards also..and this has been going on for the last few months. We go through like 12 cans of formula still a month still..but yet his doctor said he should maybe only have 2-3 bottles a day but yet he's having triple that..
