Month 6: The Six-Month Checkup
The Quick Brief
Six months marks a major pediatric milestone: the half-year well-child visit. This appointment is more comprehensive than routine weight checks—it includes developmental screening, vaccines, and a thorough assessment of your baby's growth and progress. This is your chance to get answers to accumulated questions and confirm your baby is on track. Be there.
What's Happening with Baby
By the six-month checkup, your baby has developed significantly from that curled-up newborn you first brought home. The CDC's 6-month milestones provide a framework for what pediatricians assess. Socially and emotionally, your baby should know familiar people, like to look at themselves in a mirror, and laugh. For communication, they should take turns making sounds with you, blow raspberries, and make squealing noises.
Cognitively, babies at this age put things in their mouth to explore, reach to grab toys they want, and close their lips to show they don't want more food. Physically, they should be rolling from tummy to back, pushing up with straight arms when on their tummy, and leaning on their hands for support when sitting.
The AAP recommends developmental screening at specific ages. While the standardized screening ages are 9, 18, and 30 months (plus autism screening at 18 and 24 months), the 6-month visit includes developmental monitoring and a chance to discuss any concerns. If you've noticed anything that worries you—unusual movements, lack of expected milestones, regression in skills—this is the time to raise it.
Growth metrics will be assessed: weight, length, and head circumference. These are plotted on growth curves to track your baby's trajectory. What matters most isn't hitting a specific percentile, but following a consistent growth pattern. Pediatricians look for concerning deviations from a baby's established curve.
What's Happening with Mom
The six-month mark often brings some closure to the acute postpartum period. Many of the physical recovery questions are resolved, and routines are generally more established. That said, postpartum depression and anxiety can emerge at any point in the first year, so ongoing awareness matters.
