What ways are you getting iron in your lo? Ped told me I need to give a 1/4 cup rice cereal in morning and another at night to get good amount of iron in my baby now that he's six months. Problem is, that's a lot of rice cereal! He can never finish it when I mix it into a veggie or fruit. I read it's not good to put it in a bottle due to choking reasons? 
What are you mama's doing?
