Well Child Visit: Infant - 4 months

Page in progress.

What will we do at this visit?

  • Check Weight, Length and Head Circumference and track how your baby is growing.
  • Talk about how your family is doing, feeding your baby, sleep, and safety.
  • Answer any questions you have!
  • Help your child stay healthy by keeping them up to date with their immunizations.

Will my child need immunizations at this visit?

The recommended immunization schedule protects infants and children by providing immunity early in life, before they come into contact with potentially life-threatening diseases. 

View the childhood immunization schedule to see which vaccines your baby needs.

Please note that there are age ranges for each vaccine and due to each child's individual medical history, illnesses, missed visits, travel plans, and other factors, your child may need a vaccine early, or to catch-up on missed vaccines at any age! You will discuss any needed immunizations at the time of your visit.

Feeding your baby:

  • Feed only breast milk or iron-fortified formula in the first 4-6 months.

    • Show interest in (stare, reach for) your food.
    • Are close to sitting on their own, and do not slouch when seated.
    • Put their hands to their mouth frequently.
    • Their tongue-thrust reflex is going away.
