Would this be wrong?

Sorry I’m a first time mum and just have a question. So my lo will be 1 on the 16th March. He doesn’t eat a lot of food, he just plays with it and throws it.

Would it be wrong at this ages to just give him morning milk and milk before bed and give him food instead? Or does he still really need a lot of milk?

If he just had his 2 bottles a day he would only be having 16oz of formula a day?
