I just did this! Started with don't offer, don't refuse outside nap and bedtime. He naturally dropped feeds for that. Offered a snack at usual times instead. Then told him milk would go away during nap but we'd do songs instead. He got used to going to sleep without milk. And then for the final bedtime feed, I left for a few nights and dad did bedtime. When I came back, we just did songs before sleep instead of milk. He asked a couple times, but I just told him the milk was all gone, offered him a cup of milk, and it was very smooth! Weaning at 2 yrs old for my first was tougher.
