The nervous parent asks when the big "soft spot" (anterior fontanel) will be closed. The nurse's most informative response would be

Iron-rich foods that should be recommended for a toddler with iron deficiency anemia include:

B. Chicken: Chicken, especially dark meat, is a good source of heme iron, which is easily absorbed by the body.

C. Lean Steak: Lean beef, such as steak, is also a good source of heme iron.

Non-heme iron from plant-based sources is also beneficial but is generally less easily absorbed. So, the following options are non-heme iron sources:

A. Broccoli: While broccoli contains iron, it is a non-heme iron source. It can still contribute to iron intake, but it's not as efficient as heme iron from animal sources.

D. Carrots: Similar to broccoli, carrots contain non-heme iron, but they can be part of a balanced diet for increasing iron intake.

E. Whole Milk: Whole milk can interfere with iron absorption in the body. It's not recommended for children with iron deficiency anemia, as it can make the condition worse. It's better to choose lower-fat milk or alternative milk sources.

Additionally, other sources of iron-rich foods for toddlers can include fortified cereals, legumes (like lentils and beans), and fortified infant formulas if needed. Always consult with a healthcare provider for specific dietary recommendations based on the child's condition.

A. "That big soft spot will be covered in bone by the end of the second month" is not accurate. The closure usually occurs later than the second month.

B. "The big soft spot will close at around 24 months of age" is an overestimation of the typical closure time. It is usually closed earlier than 24 months.

C. "The big soft spot is usually closed between 12 and 18 months of age."

The anterior fontanel is the soft spot located on the baby's head, and its closure is a natural part of an infant's development. The timing of closure can vary from one child to another. However, the typical range for the closure of the anterior fontanel is between 12 and 18 months of age. This information provides a general guideline for parents while acknowledging the natural variability in child development.

D. "Babies' soft spots close at different times depending on their growth rate" is true to some extent, but providing a general range (option C) is more informative for parents.
