So, if your breast milk composition changes to tailor to what your baby needs at that stage of development, does it do much good to freeze breast milk and store it for months? because freezing milk when your baby is 4 weeks and then giving it to them at 6 months won't really fill them and/or give them what they need at thst point, right? Not to mention freezing it destroys a lot of antibodies anyways. Just curious because I always make it a point to freeze and store for no good reason really. It's "just to have". is there any point?
