I need help

So my son is turning 1 in two weeks. He’s been formula fed. I plan on taking him off formula and switching to milk. But the thing is should you do bottles the same as you do now If they are on a schedule of when they usually get a bottle? Or switch to less bottles a day? Should you stay at the same amount of ounces as well? I’m so confused. Also he’s not big on human food it’s been so hard to push that he has very few things he likes. How much a day should he really be eating of human food? I feel like I’m trying to shove food down him and he barely wants it. What do I do with that?
