Between 6 and 9 months, babies are usually sitting, babbling, reaching and lighting up at familiar faces, and small differences in pace are normal. Seek a developmental check if your baby has no head control, very stiff or floppy muscles, little interest in people or sounds, no reaching or grasping, no babbling, or has lost a skill once gained. These are reasons to assess early, not a diagnosis, because support at this age works best.

*Watching your baby grow at 6 to 9 months — the rolling, babbling, reaching and giggling — is one of parenting's quiet joys, and noticing the gaps is loving attention, not worry.*

## In short
Most babies between 6 and 9 months are busy sitting, babbling, reaching, mouthing toys and lighting up at familiar faces — and small differences in pace are completely normal. The time to arrange a gentle developmental check is if your baby is **not holding their head steady, shows little interest in people or sounds, isn't reaching for or grasping objects, makes no babbling sounds, seems unusually stiff or very floppy, or has lost a skill they once had**. None of this is a diagnosis — it simply means a clinician's calm look is wise now, because support at this age works beautifully.

## What to watch at 6–9 months
By this age, most babies are starting to sit, transfer toys hand to hand, and respond to their name. Gentle flags worth a clinician's eye include:

- **Head and trunk control** — head still wobbling at 6 months, or unable to hold steady when supported sitting.
- **Muscle tone** — limbs that feel very stiff or very floppy, or a baby who consistently uses only one hand or side.
- **Reaching and grasping** — not reaching for toys, or not bringing objects to the mouth by around 6–7 months.
- **Sounds and connection** — no babbling ("ba-ba", "da-da"), no smiling back, little eye contact, or not turning towards voices and sounds.
- **Loss of skills** — any skill (a smile, a babble, a grasp) that was there and then fades. This always deserves prompt review.

The aim is never alarm — it's that an early, calm observation turns small questions into early opportunities.

## When to act
If you notice loss of a skill, very stiff or floppy muscles, or no response to sounds or people, arrange a developmental check now rather than waiting. Trust your parent instinct — what you see every day at home is valuable information for a clinician.
