Milk vs. solids

How many of your 1 year olds are still drinking a lot of breastmilk?

My son eats three solid meals a day, and still drinks a ton of milk on top of that (I’d say about 20-25 ounces a day). I’ve also started mixing in cows milk with my breastmilk to transition him, and I want to cut back on how much milk he drinks since it’s recommended 1 year olds cap their cow milk consumption to about 24 ounces a day.

I’m not sure to how cut him back slightly on the milk because he turns into a monster when he doesn’t get his milk. Anyone have any tips or tricks?
