My pump weaning experience, starting at 12 mos, and our current nursing routine at 18 mos, is very similar to what Debbers describes.
We also don't give cow milk because my son rejected it! It's more common than you probably realize for children to not like cow milk. And my son started rejected expressed breastmilk too and wanting it only from the tap So he does solids & water at daycare and it didn't seem to raise any eyebrows. I don't really worry about a milk alternative because he still nurses at least 4-5x/24 hrs.
