The first 6 months of life are full of small but powerful milestones—your baby begins to move, react, smile, and connect. But what if your baby doesn’t seem to be keeping up?

As a pediatrician, I often remind parents that while every child grows at their own pace, there are certain signs that should not be ignored. Catching delays early—especially in these first months—can make all the difference.

This article will walk you through what to expect, what may be a red flag, and what to do next.

What to Expect by 6 Months

Here are some typical developmental milestones your baby should be reaching by 6 months of age:

Motor

  • Lifts head steadily during tummy time

  • Rolls from tummy to back (and vice versa by late 6 months)

  • Pushes up on arms when lying on belly

  • Begins to sit with support

  • Opens and shuts hands, brings hands to mouth

Language

  • Coos and makes vowel sounds (“ah”, “oo”)

  • Laughs out loud

  • Turns head toward sound

Social & Emotional

  • Smiles at familiar people

  • Enjoys looking at faces

  • Shows excitement when seeing caregiver

Cognitive

  • Looks at nearby objects and follows them with eyes

  • Brings things to mouth

  • Starts reaching and grabbing toys

Red Flags: Signs That Warrant Concern

If your baby shows any of the following signs, it’s a good idea to consult your pediatrician for a developmental evaluation.

By 2–3 Months:

  • Does not respond to loud sounds

  • Does not follow moving objects with eyes

  • Doesn’t smile at people

  • Doesn’t bring hands to mouth

  • Has very stiff or very floppy body tone

By 4–6 Months:

  • Doesn’t show affection for caregivers

  • Doesn’t roll over in either direction

  • Cannot hold head steady

  • Doesn’t laugh or squeal

  • Doesn’t reach for things

  • Doesn’t push down with legs when feet are placed on a firm surface

If you notice more than one of these signs—or if you have a gut feeling that something is off—it’s important not to wait.

What Should Parents Do?

If you notice red flags:

  • Trust your instinct—you know your baby best.

  • Discuss concerns with your pediatrician. Don’t wait for the next routine visit.

  • Request developmental screening—tools like the Denver II or ASQ may be used.

  • Start early therapy if needed—even simple exercises at home can help.

What Could These Signs Mean?

A red flag doesn’t always mean there is a permanent problem. Some common causes of early developmental delay include:

  • Prematurity

  • Vision or hearing impairment

  • Muscle tone disorders (like hypotonia)

  • Genetic or neurological conditions

  • Environmental deprivation

Sometimes, delays are temporary and improve with support. But the earlier we step in, the more we can help your child succeed.

What’s the Next Step?

  1. Track development weekly.

  2. Book a consult if delays are persistent.

  3. Ask about referral to early intervention programs (especially for high-risk infants).

  4. Don't panic—early help is available.
