Key Takeaways
- Motor milestones are key physical skills children typically develop by certain ages, including gross motor skills like sitting, crawling, and walking, and fine motor skills like grasping toys or using a spoon.
- A delayed motor milestone means a child is not developing certain physical skills by the expected age range; delays may be mild and catch up with early support, or moderate to severe and signal an underlying developmental or neurological condition.
- Common signs of motor delay include not rolling over by 6 months, not sitting independently by 9 months, not crawling by 12 months, and not walking by 18 months.
- Motor delays can stem from many causes, such as premature birth, low or high muscle tone, genetic conditions, cerebral palsy, Developmental Coordination Disorder, autism, limited tummy time, or unknown (idiopathic) causes.
- Early intervention makes a measurable difference in long-term outcomes, and early screening is critical for identifying root causes and tailoring the right therapy.
Frequently Asked Questions
When should my child be walking, and when is it considered delayed?
Not walking by 18 months is listed as a common sign of delayed motor development. If your child misses two or more key milestones, an evaluation by a therapist is worth considering.
What are the signs my child has a motor delay?
Signs include not rolling over by 6 months, not sitting independently by 9 months, not crawling by 12 months, not walking by 18 months, difficulty grasping or manipulating toys, poor balance or frequent falls, stiff or floppy muscles, and trouble with chewing or speech.
What causes delayed motor milestones in children?
Causes can include premature birth, low muscle tone (hypotonia) or high tone (spasticity), genetic conditions like Down syndrome or muscular dystrophy, cerebral palsy or other neurological conditions, Developmental Coordination Disorder, autism, environmental factors like limited tummy time, and sometimes unknown (idiopathic) causes.
When should I take my child to a therapist for a motor delay?
Consider an evaluation if your child misses two or more key milestones, motor skills seem to regress, there is asymmetry such as always using one hand or side, feeding, chewing, or speaking appear delayed, or your pediatrician recommends therapy.
How can PT, OT, and SLP help a child with delayed motor skills?
Therapy can improve core strength, balance, and coordination, promote skills like crawling, standing, and walking, enhance fine motor skills such as grasping and writing, support self-care like dressing and feeding, and treat oral motor delays that affect speech and feeding. Therapists also use play-based approaches and may recommend adaptive tools and toys.
