just what everyone else said. =)

if you really wanted you can express what you have and keep it, put it in the freezer, and have it ready for when bub is born. so if god forbid something were to happen that you werent able to feed bub straight after birth (and i really hope it doesnt!!!) but then you have some colostrum there that even your DF can give bub. (i recommend this to women who are planning on having a csec for example and there may be delayed skin to skin etc for some reason)
I always say you cant have too much and good to have that backup there...on the other end of things you dont need it and thats just as good =)
