Worried About Your Baby’s Development? What to Observe and Do Next
A missed milestone does not diagnose a condition, but a parent’s concern deserves attention. Observe specific changes, talk with your baby’s clinician and ask about developmental screening rather than waiting without a plan.
Reviewed and updated:

Useful observations to record
- How your baby responds to faces, voices and sounds
- Whether both sides of the body move similarly
- Head control, reaching and floor movement
- Feeding, swallowing, alertness and growth concerns
- Any skill that appeared and was then lost
Monitoring is not screening
Milestone lists help families notice development over time. A validated developmental screen is a separate structured assessment used by trained professionals. Neither should be treated as a diagnosis on its own.
How to start the conversation
Use a direct sentence: “I am concerned because…” Give one or two specific examples. Ask what the clinician observes, whether screening is appropriate, when progress should be reviewed and what referral or early-intervention services exist where you live.
Do not wait for urgent symptoms
Common questions
Should I wait and see if a missing milestone appears?
If you are concerned, raise it now. Early discussion may bring reassurance, a review plan, screening or support. You do not need to prove that something is wrong before asking.
Does missing one milestone mean a developmental delay?
No. Development varies and a checklist is not diagnostic. Clinicians consider the whole pattern, health history, corrected age and direct assessment.
