When to start therapy for gross motor delay

The most reassuring answer in all of child development: the best time to start is now — because little bodies learn movement fastest in these early years.

In short

For gross motor delay, the best age to start support is as soon as you notice a delay — there is no minimum age, and earlier is genuinely better. A baby's brain is at its most adaptable in the first years of life, so gentle, play-based physiotherapy started early — even in the first few months — helps your child build strength, balance and coordination on a strong foundation. You do not need a formal diagnosis or a fixed age to begin; if your child is behind on rolling, sitting, crawling, standing or walking, a developmental check is worthwhile straight away.

Why earlier helps

• Brain plasticity is highest early. In infancy and toddlerhood the brain forms movement pathways rapidly, so therapy started young tends to take hold faster and more naturally.
• Skills build on skills. Sitting supports crawling, crawling supports standing, standing supports walking. Supporting an early step strengthens every later one.
• It prevents secondary issues. Early movement support can reduce muscle tightness or weakness that sometimes develops when a child compensates for a delay.
• It is gentle and play-led. Early therapy looks like guided play on the floor — tummy time, reaching, rolling games — never anything frightening or forceful.

A note on milestones, not deadlines

Milestone ages are ranges, not pass-fail dates. Some healthy children sit or walk a little later than average. The point is not to panic at one missed week, but to have a friendly developmental check if your child is consistently behind, has lost a skill, feels very stiff or very floppy, or strongly favours one side of the body. A clinician can tell the difference between a normal variation and a delay that benefits from support.
