For a premature baby, always track milestones by corrected age (counted from the due date) until about two years. At 3–6 months corrected, the goal isn't diagnosis but gentle watching of early movement, looking and social connection. Persistent stiffness or floppiness, a tightly fisted or one-handed preference, no response to faces or sound, or no social smile deserves a prompt clinician check — but most early babies thrive with time and support.

*If your baby arrived early and you're watching every milestone with one eye on the calendar, that careful attention is exactly the right instinct — and there's a kinder way to read the signs.*

## In short
For a baby born prematurely, the single most important thing to know is that you should track milestones by **corrected age** — your baby's age counted from their due date, not their birth date — until around two years. At 3–6 months corrected, you're not looking for a "diagnosis"; you're gently watching whether your baby is building the early building blocks of movement, looking and connecting. Most early babies catch up beautifully with time and support. Worry isn't the goal — *noticing and checking* is.

## What to watch at 3–6 months (corrected age)
Using corrected age, here are the gentle, reassuring things to look for — and the patterns worth a prompt check:

- **Settling and softening** — by around 3–4 months corrected, babies usually relax out of newborn stiffness. Persistent strong stiffness, arching, or a body that always feels floppy and "melts" is worth raising.
- **Hands and midline** — bringing hands together, opening fists, reaching toward toys. A hand that stays tightly fisted, or a strong, consistent preference for one hand this early, deserves review.
- **Head control** — by around 4 months corrected, head steadiness when held upright is emerging.
- **Looking and listening** — following your face, turning toward your voice, startling to sound. If your baby doesn't seem to fix on faces or respond to sound, mention it.
- **Social warmth** — smiling back, cooing, brightening when you appear, by around 6 weeks to 3 months corrected.

Many differences at this age simply reflect how early your baby arrived and resolve with growth. The reason to check sooner rather than later is not alarm — it's that the early months are a rich window where gentle support works wonderfully.

## The Pinnacle way
Because prematurity raises the chance of developmental wobbles, structured follow-up matters more than guesswork. A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a checklist or a single worried moment. Our clinicians always track [prematurity-related developmental risk](https://pinnacleblooms.org/ask/prematurity-developmental-risk) using corrected age, build your baby's own baseline, and, where movement or muscle tone is the question, our [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) team can begin gentle, play-based support early. The aim is reassurance and a clear plan — not a label.

## Trusted sources
WHO and Nurturing Care framework guidance on early childhood development and follow-up of preterm infants; American Academy of Pediatrics guidance on using corrected age and developmental surveillance for premature babies; CDC "Learn the Signs, Act Early" milestone resources.

**Next step —** Trust your watchfulness. [Book a developmental check](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) with a Pinnacle clinician so your baby's progress is read correctly — by corrected age, with your concerns at the centre.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
