Have any mommies gone through their babies getting low iron? My son is to take drops 3x a day for 6 weeks to make it normal. It's been 6 weeks, I called and scheduled an appointment to get his iron checked again. I'm really hoping it's where it needs to be. His level was 10.9, and they want it 11 or higher. I know it's not much difference but I always worry.
