DS is 3MO, healthy weight, and EBF. The pediatrician told me I need to start giving him infant vitamins. I havn't been doing this because I thought he gets everything he needs from breastmilk. I take pre-natal vitamins and iron supplements. Does everyone else give infant vitamins on top of this? If so, which ones do you use? I read that the vitamins can stain teeth as they come in. Are there any dye-free vitamins that you recommend?
