Some babies skip crawling and move on to bottom-shuffling or pulling to stand, and many are simply taking their time. What matters is that your baby has some way of moving to reach things and is steadily adding new skills. If there's no method of moving across the floor and your baby isn't bearing weight on the legs, a gentle developmental check brings reassurance.","q":"My 10-month-old isn't crawling yet — should I worry?"},{"a":"Track preterm babies using their corrected age — that is, age from the original due date rather than the birth date — for at least the first two years.

These are signs to observe and discuss with a professional, not to diagnose at home.","answer_md":"*Every baby pulls up, crawls and cruises on their own timeline — so how do you know when a little extra support might help?*\n\n## In short\nBetween 9 and 12 months, most babies are sitting steadily without support, getting in and out of sitting, crawling or shuffling, pulling up to stand at furniture, and beginning to cruise sideways along it. Early signs of gross motor delay include not yet sitting unsupported by around 9 months, not bearing weight on the legs when held, not attempting to crawl or move across the floor, and a body that feels persistently floppy or very stiff. These are signs to observe and discuss gently with a professional — not to diagnose at home.\n\n## Early signs to watch (9–12 months)\n**Sitting and trunk control**\n- Not sitting without support by around 9 months, or toppling often with little saving response\n- Needing to be propped, or rounding heavily through the back when seated\n\n**Moving across the floor**\n- No attempt to crawl, commando-crawl, roll or bottom-shuffle to reach a toy just out of reach\n- Rolling only one way, or not rolling at all\n\n**Standing and weight-bearing**\n- Not taking weight on the legs when held in standing, or legs that cross/scissor stiffly\n- Not pulling up to stand at furniture by around 12 months\n\n**Muscle tone and movement quality**\n- A body that feels consistently floppy (low tone) or very tight/stiff (high tone)\n- Strong, persistent preference for using only one hand or one side of the body\n- Loss of a skill the baby could previously do — this always deserves a prompt check\n\nWhat matters most is the **overall pattern** and whether your baby is steadily adding new skills, rather than any single milestone hit on an exact date. Babies born preterm should be tracked by their corrected age.\n\n## When to seek a check\nMilestones vary, and many babies who are a little behind catch up beautifully. Consider a developmental check if your baby is not sitting independently by around 9 months, shows no way of moving across the floor, does not bear weight on the legs, feels notably floppy or stiff, strongly favours one side, or has lost a skill. Early movement support is gentle, play-based and often most effective when started early — so checking sooner brings reassurance either way.\n\n## The Pinnacle way\nAt [Pinnacle Blooms Network](/), we start by watching how your baby moves, plays and explores — then build playful, parent-led activities that strengthen the trunk, legs and balance. Support such as [physiotherapy](/physiotherapy) and movement-focused therapy helps your little one find their next milestone at their own pace. 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; nothing here is a diagnosis. You can learn more about [gross motor delay](/gross-motor-delay) and how support works. Across 70+ centres in 4 states and 4.95 lakh+ families served, our aim is steady, strengths-first progress.\n\n## Trusted sources\nAligned with the developmental milestone guidance of the US Centers for Disease Control and Prevention and HealthyChildren.org, and with World Health Organization motor development milestone research. These describe typical ranges, not rigid deadlines.\n\n**Next step —** if any of these signs sound familiar, book a developmental screen with our clinical team on WhatsApp at +91 91001 81181, and let's understand your baby's movement together.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-gross-motor-delay-in-a-9-to-12-month-old","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/what-are-the-early-signs-of-gross-motor-delay-in-a-9-to-12-month-old","lang":"en","indexable":true},{"href":"https://pinnacleblooms.org/ask/what-are-the-early-signs-of-gross-motor-delay-in-a-9-to-12-month-old-te","lang":"te","indexable":true}],"dimensions":[{"key":"conditions","label":"Conditions"}],"meta_title":"Gross Motor Delay Signs: 9–12 Months","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Make floor play the highlight of the day.
