Worried your child is Anemic? We can help you understand! Iron is a mineral as essential to life as oxygen itself. While adults might readily associate iron deficiency with fatigue or weakness, for infants, it can have a more significant impact on their development and overall health. Anemia is a problem in which the body does not have enough healthy red blood cells. This blog aims to shed light on iron deficiency in infants, helping parents understand its causes, symptoms, and most importantly, what can be done to prevent and address it.


Iron deficiency anemia in infants and toddlers can have several causes. One of the primary reasons is a lack of iron in the diet. Infants who are exclusively breastfed may not receive enough iron if the mother has low iron levels. Additionally, infants who are born prematurely or have a low birth weight are at a higher risk of developing iron deficiency anemia.

There are various other causes which can be duly noted as

1.Depleted Iron Stores: 

Infants rely on iron stores inherited from their mothers during pregnancy. These stores typically last for the first 4-6 months of life.expand_more However, factors like:

  • Premature birth: Premature babies have less time to build up iron stores in the womb, making them more susceptible to deficiency.
  • Low iron stores in the mother: Mothers with iron deficiency themselves might have limited iron to pass on to their babies.

2. Dietary Deficiencies: After 6 months, dietary sources become crucial. Iron deficiency can occur if:

  • Non-fortified formula: If formula feeding is not supplemented with iron-fortified formula, babies can become iron deficient.
  • Delayed introduction of iron-rich solids: Starting solid foods later than 6 months can delay iron intake, especially if the introduced foods are not rich in iron.
  • Limited intake of iron-rich foods: Picky eating habits or a diet lacking in iron-rich options can contribute to deficiency.

3.Medical Conditions: 

  • Chronic blood loss: Conditions like gastrointestinal bleeding can lead to iron loss.
  • Celiac disease: This autoimmune disease can interfere with iron absorption from food.expand_more
  • Multiple Births: Twins or triplets may have lower iron stores due to sharing limited prenatal resources from the mother.

4.Additional Factors:

Early Cord Clamping: Delayed cord clamping, a practice where the umbilical cord is not immediately clamped after birth, can provide an additional iron boost to the baby.


There are many nutritional deficiencies accompanied by signs and symptoms. The symptoms of iron deficiency anemia in infants and toddlers can vary, but some common signs include:

  • Paleness - Noticed in the inner eyelids or gums
  • Slow growth - In the infant's height and weight
  • Irritability - Often manifested in the form of crying and a cranky demeanor
  • Fatigue - Infants turn less playful and listless
  • Weakness - Muscles that lack sufficient iron for oxygen transport will struggle to perform, leading to general weakness and a lack of energy for play and development.

Exams and Tests

To diagnose iron deficiency anemia, healthcare providers may perform blood tests to measure the levels of hemoglobin and iron in the blood. They may also evaluate the size and shape of red blood cells to determine the type of anemia.The most common blood test is a Complete Blood Count (CBC) to assess red blood cell size and count. A ferritin test measures iron stores, and an iron level test checks circulating iron. These tests help your pediatrician definitively diagnose iron deficiency and determine the best course of treatment.


Treating iron deficiency anemia in infants and toddlers typically involves iron supplementation and depends on severity and age. It often involves dietary changes like iron-fortified formula, iron-rich foods, and vitamin C to aid absorption. In moderate cases, liquid iron supplements might be prescribed. Regular blood tests monitor progress and ensure long-term iron sufficiency is maintained through continued dietary focus on iron-rich options

Outlook (Prognosis)

With proper treatment and management, most infants and toddlers with iron deficiency anemia can recover fully. It's crucial to monitor their iron levels regularly and make dietary changes to prevent future deficiencies. Preventing deficiency is ideal, achieved through prenatal care, breastfeeding, iron-fortified formula, and introducing iron-rich foods when starting solids. Consulting your pediatrician ensures your baby has the iron needed for a healthy start in life.

Possible Complications

If left untreated, iron deficiency anemia in infants and toddlers can lead to complications such as delayed growth and development, cognitive impairments, and an increased risk of infections.


Preventing iron deficiency anemia in infants and toddlers involves ensuring an adequate intake of iron-rich foods. Healthcare providers may also recommend iron supplementation for at-risk infants or those with low iron levels.
