It is vital for fetus to have adequate iron during gestation is because breast milk which is the main food of the baby is low in iron. Hope this is the right answer on this scenario and this would then be of big help then.

If it's a smaller child or infant, place one on the middle of the chest and on the child's back. (if it is a bigger child with enough room for two, place one on the upper right/your left of the chest, and one on the lower left/your right) the pads should never touch each other.
