Reply to Nutrition: stored milk from months ago vs. formula

Yes that's true Jenine, it's still good for drinking. I'm referring to how the nutritional composition of the milk we produce changes as the baby grows, starting with colostrum, to transitional milk, to mature milk, etc. So milk produced for, say, a newborn will be different from milk for a six month old. I'm worried that the milk I froze when the baby was younger, though still ok to drink, won't have the nutrition the baby needs now that he's older.
