My child was born in September. I am currently nursing an almost 3yo as well. I have some milk from within the first few months he was born as well as milk from this month. I am a healthy 32yrold woman, I take prenatal and multivitamins daily, as well as calcium, vitamin D, fiber and probiotics. I do not smoke anything. I do drink occasionally but when I do I do not pump or store BM from that time frame.
