I've been told that LO should switch from formula to whole milk by the time he's a year old, and the recommendation is also to not use bottles by that point. He's almost 11 months and I feel totally confused how to approach any of this, so would appreciate some insight from those who've gone through the transition!

My main questions are:
-He currently drinks 4 bottles during the day, about 6 ounces each. How do I start cutting those feeds down/out?
-The little guy is not proficient at all with holding a cup. He also doesn't feed himself! So I'm not sure how to transition to giving milk in a cup...
-Do I need to slowly introduce whole milk, or I just change it over cold turkey?

Any tips appreciated!
