I'm probably overthinking this but I was wondering if anyone has an answer. I understand that the breastmilk I am producing today is tailored to meet the current nutritional needs of my daughter and that the breastmilk I have frozen from August was tailored to meet the nutritional needs she had when she was only a few weeks old. Breastmilk is good for up to a year in my deep freeze but should I really be giving my daughter milk that I pumped so many months ago if it's not tailored to meet her needs? What's the most ideal use of a freezer stash if hypothetically I have all the milk she needs until she's 6, 8, or 10 months old? If at 8 months old I start giving her 100% freezer stash that starts in August, would that be ok? I tried finding info on this on google and Kelly mom but I'm not finding the specific answer I'm looking for. And my mind is just about blown with tandem nursing - if a mother is nursing a toddler and a newborn, who is that milk tailored for?!? Like I said I'm probably overthinking this but I was curious if anyone has any info.
