My Toddler Can't Turn a Doorknob
The short answer
Turning a doorknob requires wrist rotation (supination/pronation) that typically develops between 2-3 years. Most toddlers under 2 cannot turn a doorknob, and this is completely normal. This is an advanced fine motor skill that requires hand strength and wrist mobility.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Toddlers at this age do not have the wrist rotation or hand strength to turn a doorknob. They may reach for knobs and try to turn them. This interest is a good sign even if they cannot accomplish the task.
Some toddlers begin to develop the wrist rotation needed, but most cannot turn a round doorknob. Lever-style handles are easier. If your toddler can turn large knobs or dials, wrist rotation is developing well.
Most children learn to turn doorknobs during this period. If your child cannot turn any knobs or dials by age 3, evaluation of hand strength and wrist mobility may be helpful.
Doorknob turning should be mastered. If your child has persistent difficulty with twisting and turning motions, an occupational therapist can assess and address wrist and hand function.
What Should You Do?
When to take action
- Your toddler is under 2.5 years and cannot turn a doorknob.
- Your toddler can turn large dials and knobs but not doorknobs.
- Your toddler is developing wrist rotation skills with other activities.
- Your toddler shows interest in turning things even if not yet successful.
- Your child is over 3 and cannot turn any knobs or twist objects.
- Your child seems to have limited wrist rotation in general.
- Your child has difficulty with other fine motor tasks involving hand rotation.
- Your child has lost wrist or hand function.
- Your child has pain or swelling in their hands or wrists.

My Toddler Can't Twist or Unscrew Lids
Unscrewing lids is an advanced fine motor skill that combines wrist rotation, grip strength, and bilateral hand coordination. Most children learn to unscrew loose lids between 2 and 3 years. If your toddler is under 2 and cannot unscrew lids, this is completely normal.
My Baby Has Overall Fine Motor Delays
Fine motor skills develop gradually from grasping rattles to using a pincer grip to scribbling and stacking. If your child seems behind in multiple fine motor areas, an occupational therapy evaluation can identify specific areas to work on. Many fine motor delays respond very well to targeted therapy and practice.
My Baby Has a Weak Grip
Grip strength develops gradually over the first year. Newborns have a reflexive grasp that fades around 3-4 months, and voluntary grasping then takes over. Dropping objects frequently is completely normal for young babies who are still developing hand control. If your baby shows no interest in grasping at all by 4-5 months or cannot hold objects briefly by 6 months, talk to your pediatrician.
My Baby Seems to Use One Side More Than the Other
Babies should use both sides of their body fairly equally during the first 18 months of life. While slight preferences can be normal, a consistent pattern of favoring one side - using one arm much more than the other, crawling with one leg dragging, or turning the head predominantly one way - should always be discussed with your pediatrician. Early identification of asymmetry leads to the best outcomes.
My Baby Only Army Crawls
Army crawling (also called commando crawling) is a completely valid and normal way for babies to move. Many babies army crawl for weeks or even months before transitioning to hands-and-knees crawling, and some skip hands-and-knees crawling entirely. What matters is that your baby is independently mobile and exploring their environment.
One Side of My Baby's Body Moves Differently
Babies should generally use both sides of their body equally. If one side consistently moves differently, is weaker, stiffer, or less coordinated, this warrants evaluation. Asymmetric movement can indicate hemiplegia (cerebral palsy affecting one side), brachial plexus injury, or other neurological conditions that benefit from early therapy.
