Sorry, Verbier, I should have been more specific

.
My youngest is breast snob and can only be convinced to take the bottle when she's desperately hungry...maybe

. My MIL has a habit of offering her a bottle not long before I am due to arrive. Usually I walk in while the bottle is being warmed up

. She warms up the full 3 oz. of milk, which my daughter then refuses to take. I then have to toss that milk since it's already been heated

. I was hoping that I could freeze 1 oz. increments of milk
in addition to the 3 oz bags I already freeze. This way I could tell my MIL that the bags are for during the day and the 1 oz. cubes are to tide her over until I arrive.
