Goats or a soy milk can also be a good idea... We were BF, so diff journey than yours and MJ was still having feeds from me, but i used soy milk and goats occasionally (she didnt like it though, so we stopped that quickly) in food or drinks and then transitioned from these to cows milk.
My sister found milk upset her as a child, so wanted to try gentler options.

Great suggestions MR (gotta share the love thou )
