not sleeping through the night help*update in comments*

My son has recently become an excellent napper and has a great internal clock. He wakes up at 8:30am exactly. Goes for nap at 11:00-12:30. Goes for another nap at 3:00-4:00. Like clockwork. He falls asleep for bed between 8:45-9:30 though he isn't set on a specific time even though we always start his sleep time routine at 8:25ish. throughout the night he wakes up VERY often and the only way to get him to go back to sleep is a bottle. He has 3 to 4 bottles a night each with 4oz or 6oz. So he's waking up probably 5 times total from 8:30-8:30 (he sobs and sobs until I feed him and falls asleep while drinking the bottle even though he loves his pacifier and it isn't good enough for him when he's sobbing) . Can anyone help me out here? He eats A LOT during the day. Breakfast 1 piece of buttered toast. Lunch whole banana and cheese. Dinner whatever we eat usually potatoes and chicken until he doesn't want anymore. And a snack sometime during the day. He also eats around 26-30oz during the day time. Can anyone tell me what im doing wrong?
