I am not on formula but I started my son on food when he was 5 months. He never seemed satisfied with the amount he was getting but baby food makes him the fullness feeling that keeps him happy. I say slowly start and always offer a bottle either before or after.

my daughter eats about half a bottle of baby food then 6oz of formula 2 times a day. and 8oz every feeding without baby food.

I started feeding my son baby food and he loved it helped space out bottles as well he went through 11-12 cans a month until he was almost one. but I feed him baby food and then he'd eat a whole 4-6 oz bottle afterwards he loved food

always offer formula first and food after basically to learn textures and taste...eventually as my daughter got older she wanted less formula but at 10 months she still get 3 bottles a day.

Babies need milk till a year old but I just started testing out fruits and veggies out. I also put some in baby cereal and he liked it :)

8-9 cans a month really isn't that bad we used more

Food before one is just for fun he needs to continue drinking formula for atleast the first year and you give him one kind a week to make sure he isn't allergic
