A single soft week is not the worry — persistence across home, playground and preschool is. Any loss of established skills or new one-sided weakness needs prompt medical review. Hypotonia has many treatable causes, and early assessment finds the why and starts strengthening support.","answer_md":"*If your four-year-old still feels unusually floppy, tires quickly, or seems to slump where other children stay upright — your noticing is worth acting on.*\n\n## In short\nBy four years, a child's muscles should hold them steadily for running, climbing, sitting up at the table and gripping a crayon. [Hypotonia](/hypotonia-low-muscle-tone) — lower-than-usual resting muscle tone — is worth a prompt developmental check if your child seems persistently floppy, tires far faster than peers, slips out of your hold, has a wobbly or unusual gait, or struggles with stairs, jumping and self-feeding. This is a sign to investigate, not a diagnosis — and many causes are treatable when found early.\n\n## What to watch for at four\nLow tone shows up in everyday effort. Compared with other four-year-olds, gently note whether your child:\n\n- **Tires or slumps quickly** — leans on furniture, lies down often, or props their head on their hand at the table.\n- **Has loose, very flexible joints** — knees, elbows or wrists that bend further than usual, or a tendency to sit in a wide \"W\".\n- **Struggles with whole-body skills** — running, jumping with both feet, climbing stairs without holding on, or pedalling a tricycle.\n- **Finds fine tasks hard** — a weak crayon grip, drooling, difficulty chewing tougher foods, or unclear speech with an open mouth posture.\n- **Walks unusually** — a wide-based, wobbly or unsteady gait, or frequent falls.\n\nA single soft, bendy week is not the worry. **Persistence** is — if these patterns hold across home, playground and preschool over several weeks, that is the time to seek a clinician. Importantly, also seek prompt medical review if you notice any *loss* of skills your child had before, or new weakness on one side.\n\n## When to refer\nBecause low tone can stem from many causes — some neurological, muscular or metabolic — a four-year-old who is persistently floppy or whose motor skills lag behind peers should be reviewed by a paediatrician or developmental clinician without long delay. Early assessment finds the *why*, rules out treatable medical causes, and starts the physical and occupational therapy that builds strength, posture and confidence during these high-growth years.\n\n## The Pinnacle way\nThis is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated), a clinician-administered structured assessment, and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care.
