Re: Weaning from pumping/breastmilk while I work?
As long as you are still nursing 3-5 times a day you don't need to replace your breast milk with any kind of milk alternative unless you just want to. I think you'd be fine proceeding as you've planned, though I'd wait to start night weaning until you know for sure he's taking plenty of coconut milk and a variety of solids.
