We were told to start Fer-In-Sol twice a day because DD's hemoglobin was a little low (9.7).
I'm debating whether I should try to add more iron-rich foods into her diet instead, though she's generally not a big eater. Getting her D drop in once a day is a struggle and I imagine the iron tastes much worse.
We are planning to start combo feeding after the New Year, so she'll get one 4oz bottle of formula at DC. I'm also wondering if that will take care of things.
