Re: slight anemia
Low iron is a fairly common problem with babies who were born early, but even term breastfed babies can become anemic if they have a predisposition to anemia or- hypothetically- if mom has been anemic and has been producing milk with lower than average iron content. Cord management at birth can play into the issue- babies who are born with immediate cord clamping (as opposed to delayed clamping) will get less blood from the placenta, and therefore less iron.
Poly-vi-sol is an easy way to get baby's iron up, but if you don't want to give that, you can choose an iron-only supplement. You also want to offer plenty of iron-rich solids, which include leafy greens (especially spinach), meats, fish, beans, and dried fruits like apricots.
