A 6-month-old does not have to sit independently or crawl. At around this age, supported sitting, leaning on the hands, rolling, reaching and pushing up are all useful parts of the movement picture. The NHS says crawling commonly begins around 7 to 10 months, and not every baby uses a classic hands-and-knees crawl. Look for gradual progress—not a race to one skill.
What is reasonable to expect at 6 months?
An NHS community development guide describes sitting with support and leaning on the hands while sitting at around 6 months. A baby may balance briefly, fold forwards into a tripod position or topple when reaching. That is different from getting into sitting and staying there independently.
The same guide includes getting into a crawling position among skills that may appear around this age, but calls every milestone a rough guide. It does not mean a baby must travel across the floor by 6 months.
| What you notice | How to understand it |
|---|---|
| Sits with your support | Fits the broad 6-month picture. |
| Leans forwards on both hands to balance | A common step while trunk control develops. |
| Sits alone only briefly or not yet | Independent sitting is not a 6-month pass-or-fail test. |
| Rocks, pivots or gets onto hands and knees | These can be early ways of preparing to move. |
| Is not crawling | Usually not concerning by itself at 6 months; NHS guidance places crawling commonly around 7 to 10 months. |
Does crawling have to happen in one particular way?
No. NHS Best Start in Life says babies will probably begin crawling around 7 to 10 months, but some bottom-shuffle and not all babies crawl. Others roll, pivot, commando-crawl or move between sitting and the floor in their own sequence.
The useful question is not whether the movement looks exactly like another baby's. Notice whether your baby is gaining control, using both sides of the body, reaching for objects and finding new ways to change position over time.
Does readiness for solid food require independent sitting?
The NHS describes one of the three signs of readiness for solid food as being able to stay in a sitting position and hold the head steady. It does not say a baby must get into sitting alone, remain unsupported on the floor or crawl before starting.
All three readiness signs should appear together from around 6 months: steady head and sitting posture, hand–eye–mouth coordination, and swallowing food rather than pushing it back out. Plan the start with your health visitor or GP if you are unsure, especially after a premature birth or when there are feeding or developmental concerns.
How can you support movement without forcing it?
Offer supervised floor play while your baby is awake: time on the back to kick and reach, tummy time, toys placed within or just beyond easy reach, and supported sitting with you close enough to prevent a fall. Short opportunities spread through the day let your baby practise their own transitions.
The NHS advises limiting long periods in walkers, bouncers, reclining carriers and seats that prop a baby in sitting. These devices do not teach the balance needed for independent sitting, and heavy use can delay movement skills. Tummy time is for awake, supervised play only; continue to place your baby on their back for sleep.
When should you speak to a health visitor or GP?
Contact your health visiting team or GP if your 6-month-old cannot control their head in supported sitting, is not reaching for and holding toys, keeps their hands tightly clenched, does not push the head and shoulders up during tummy time, or shows little movement progress. Ask sooner if your baby loses a skill, seems unusually stiff or floppy, or consistently moves one side much less than the other.
If your baby was born prematurely, NHS reviews use developmental age calculated from the original due date until age 2. Your health visitor can help you interpret progress using corrected age. You do not need to wait for the routine 9-to-12-month review when something worries you. If there is a sudden loss of movement with a seizure, breathing difficulty, blue or grey colour, collapse or unresponsiveness, call 999.
