Once your baby is consuming more than 4-6ounces of milk every 3-4 hours, it could be time for cereal if your baby is a few months old and has no issues with texture. It does need to be quite watered down and most kids aren't ready for spoons until they can sit up well enough on their own. If you have breast milk frozen in thick plastic sterile containers, it should be good for about 4 months in a deep freeze that's not opened all the time. Once it is thawed, the lymphocytes (which are normal) in the breastmilk have died or become dormant and have diminished protective capacity over the freshness of the milk, so it should be used within 24 hours after being completely thawed. You can give breastmilk to a baby throughout infancy, and there are some women who will still give breastmilk to their children when they are talking. It doesn't matter if you mix the breastmilk with the formula or give them separately.
