Just found out one of my 2-year-old twins is anemic. Our pedi is recommending iron supplements BUT he has had issues with constipation, shows no outward symptoms of anemia and I am just feeling hesitant about them. He does not eat meat. Will not try one bite, is very physically strong and will contort himself in a way that no meat will ever come within two feet of his mouth. Tips on ways to help increase his iron intake? Doing more googling but thought I'd check here!
