My take on this is that there are ANTIBODIES / IMMUNITIES in breastmilk always, but that colostrum does not persist beyond the early time. At some point it becomes transitional and then mature milk, not exactly the same for everyone and it is a gradual process not a discrete one, but I do not believe colostrum (a unique form of mammalian milk in the early days) is ALWAYS in breastmilk.
