These are signs to check, not a diagnosis — many causes are very treatable and early therapy helps.","answer_md":"*When your little girl feels a touch softer to hold, or seems to take her time with sitting and standing, your instinct to look closer is exactly the right one.*\n\n## In short\nLow muscle tone (hypotonia) in a 1-year-old often shows as a baby who feels 'floppy' to hold, slips through your hands when lifted under the arms, sits or pulls to stand later than peers, and tires quickly during play. These are signs worth checking — not a diagnosis. Many causes are gentle and very treatable, and early therapy makes a real difference, so a developmental check is the kind, sensible next step.\n\n## Early signs to gently watch for at around 1 year\n**How she feels and holds herself**\n- Feels soft or 'floppy' when carried, with a sense that she might slip through your hands when lifted under the arms\n- Head still lags or feels heavy when she's pulled gently from lying to sitting\n- Tends to rest in 'frog-leg' posture — legs splayed flat and wide — when lying on her back\n\n**Movement and milestones**\n- Sitting without support, crawling, or pulling to stand arriving later than expected\n- Not bearing much weight on her legs when held standing, or knees that buckle\n- Prefers W-sitting or slumping rather than an upright, steady posture\n\n**Everyday signs**\n- Tires quickly during play, or seems to prefer staying still\n- A weak or soft cry, or feeding that is slow, with poor suck or some dribbling\n- Joints that feel unusually loose or 'bendy'\n\n## When to seek a check\nHypotonia is a *sign*, not a disease in itself — it has many possible causes, several of them very manageable. Please book a developmental check soon if you notice these signs together, and seek prompt medical advice if there is any loss of skills she once had, difficulty with feeding or breathing, or if she feels markedly weaker over time. Early support through [physiotherapy](/physiotherapy) and play-based strengthening helps build the foundations for sitting, standing and walking with confidence.\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 the care of qualified clinicians — never from an online list or a worried evening of searching.
