10.6 is kinda low. What type of iron is in the drops? Ferrous sulfate is the most common but is also the roughest on the body and is not well-absorbed. Your ds might get an upset tummy andconstipation.
I'm surprised that she told you to nurse less. Breastmilk is an excellent source of iron. Cow's is not, and iron-rich foods should not be taken with dairy, because dairy inhibits iron-absorption.
These things hinder iron-absorption:
antacids, dairy, soy, tea, coffee, high-fiber foods, and solids consumed right after breastfeeding.
Egg yolks have lots of iron, but it is not well-absorbed. Same for spinachand legumes. Eating these foods with Vitamin C will help you get the iron from them.
Vitamin C really helps you absorb iron. Meat, poultry, and fish eaten with iron-rich plant foods also help you get iron from them.
Foods highest in iron that is well-absorbed: liver and red meat. I know, yuck. I'm vegetarian, so it doesn't work for me.
Dried fruit (esp. apricots and prunes), whole grains, nuts (I think), and wheat germ are good. Fortified cereals like cream of wheat or cheerios might work for you but can be constipating--and don't serve them with milk. Red grapes are also good.
Cook in cast iron. Eat tomato sauce with whole grain pasta. Eat skins on potatoes.
There are iron supplements that are better and easier to take. Ferrous fumarate and others might be available for kids by prescription. I took a great supplement called anemagen when pregnant--it has other vitamins as well. You might ask your ped. for alternatives.
I took most of this from the Family Nutrition Book by Sears--it's great and has much more.
