Check with a clinician if your baby cannot sit unsupported at 9 months, has no way of moving themselves at 12 months, cannot bear weight on their legs, feels stiff or floppy, or strongly favours one side. A single late skill is usually fine; a cluster, a one-sided pattern or a loss of skills deserves prompt review.","answer_md":"*If you're watching your baby near their first birthday and wondering whether they should be doing more by now, that careful attention is exactly what helps most.*\n\n## In short\nBetween 9 and 12 months, most babies are sitting steadily without support, getting in and out of sitting, and beginning to crawl, pull to stand or cruise along furniture. It's worth a friendly developmental check if, by around 9 months, your baby still cannot sit without help, or by 12 months shows no attempt to move themselves around (rolling, scooting, crawling), cannot bear weight on their legs when held, or has clearly stiff or floppy muscles. These are reasons to look — never reasons to panic, because babies arrive at milestones along a normal range.\n\n## What's typical at 9–12 months — and what's worth checking\nGross motor skills are the big-body movements: head and trunk control, sitting, crawling, standing. In this band, a broad and healthy range is normal — some babies bottom-shuffle instead of crawl, some skip crawling entirely. What matters is steady *forward progress* and good muscle tone. Speak to a clinician if you notice:\n\n- **Sitting** — by 9 months, still cannot sit steadily without being propped or held.\n- **Movement** — by 12 months, no way of getting around at all (no crawling, rolling, scooting or shuffling).\n- **Weight-bearing** — legs collapse or won't take any weight when you hold your baby upright.\n- **Tone** — limbs feel unusually stiff or unusually floppy, or one side seems used much less than the other.\n- **A loss** — any skill your baby clearly had, then stopped doing.\n\nA single late skill in an otherwise thriving, alert, engaging baby is usually nothing to worry about. A cluster of these, a strong one-sided preference, or a loss of skills deserves a prompt look.\n\n## The Pinnacle way\nA 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 an online checklist or a single observation. Our clinicians build your baby's own movement baseline, look gently for any cause, and shape early, play-based support around their strengths. If movement is the worry, our [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) and physiotherapy teams can begin warm, structured support, and you can read more about [Gross Motor Delay](/gross-motor-delay) in plain language. Early support in infancy is some of the most effective there is.\n\n## Trusted sources\nWHO milestone and nurturing-care guidance; American Academy of Pediatrics developmental surveillance; CDC \"Learn the Signs, Act Early\" milestone checklists for 9 and 12 months.\n\n**Next step —** Trust what you've noticed. [Book a developmental assessment](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) so a Pinnacle clinician can review your baby's movement with you — early and reassuringly.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-9-to-12-month-old-might-have-gross-motor-delay","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-9-to-12-month-old-might-have-gross-motor-delay","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/when-should-i-worry-that-my-9-to-12-month-old-might-have-gross-motor-delay-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Gross Motor Delay at 9–12 Months: When to Worry","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Give plenty of supervised floor time on a firm surface each day — tummy time, reaching for toys just out of grasp, and sitting practice.
