I need to start supplmenting my DD's bottles with formula, but only a little - like 1 oz/bottle. I am just a little short each bottle. I have never mixed formula and have no idea how to go about this. I read that you have to throw away formula if it is not finished. So do I literally have to mix up 1 oz of formula every time? I usually send storage bags with my breastmilk in them. Can I i just add in 1 oz of mixed formula or does this have to be done fresh with each bottle at daycare? Sorry if these questions are stupid, but I have negative experience with formula.
Re: Need to supplment - how?
