Changing from formula to full fat milk

Yeah I was thinking of starting next week. My boy will be 11 months on the 1st. But not sure on how to go about it!

I’ve read somewhere (sure it was solid starts website) you start with 1-2oz so they get used to the taste/digesting it. Not sure where you go from there sorry but assuming you build it up and wean off formula milk? That’s what I plan on doing anyway 😅
