Delayed Hand Dominance
The short answer
Hand dominance - a consistent preference for using one hand over the other - typically becomes clearly established between ages 2 and 4, though it can take until age 5 or 6 in some children. It is completely normal for toddlers under 2 to switch hands frequently. Using both hands equally at this age does not mean anything is wrong and actually shows good bilateral coordination.
By Age
What to expect by age
Babies at this age use both hands freely and should not show a strong hand preference. They reach with whichever hand is closer to the object and transfer items between hands easily. A very strong preference for one hand before 12 months can actually be a concern, as it may indicate weakness or neurological differences on the non-preferred side. Babies should be using both hands actively at this age.
Toddlers begin to show a slight preference for one hand for certain tasks, but they still switch hands frequently. You may notice your toddler prefers one hand for eating and the other for stacking blocks, or they may switch back and forth within the same activity. This is all normal and expected. There is no need to encourage or direct hand preference at this age.
Hand preference becomes more consistent during this period, though some children still switch hands. Most children will show a clear preference for one hand during activities like drawing, throwing, and eating by around age 3. If your child is still switching hands frequently at this age, it is usually not a concern as long as they are developing fine motor skills appropriately with both hands.
Hand dominance should be clearly established by age 4 to 5 for most children. If your child is over 4 and still has no consistent hand preference, and this seems to be accompanied by difficulty with fine motor tasks like drawing, cutting, or buttoning, an occupational therapy evaluation may help. Some children are naturally more ambidextrous, and as long as they can complete fine motor tasks effectively, there may be no concern.
What Should You Do?
When to take action
- Your child is under 2 years old and uses both hands equally, switching between them freely.
- Your toddler shows a preference for one hand during some activities but switches for others.
- Your child is between 2 and 4 years old and gradually showing an emerging hand preference, even if it is not fully consistent yet.
- Your child seems to be ambidextrous but can complete fine motor tasks well with either hand.
- Your child is over 4 years old and has no hand preference at all, and this seems to be making fine motor tasks like drawing or cutting more difficult.
- Your child seems to avoid using one hand entirely, which may indicate weakness on that side rather than true hand preference delay.
- Your child had a clear hand preference and has lost it, or has started showing weakness in their dominant hand.
- Your baby under 12 months shows a very strong preference for one hand and avoids using the other hand at all, as early hand dominance can indicate weakness or a neurological issue on the non-preferred side.
- Your child has sudden weakness or loss of function in one hand after previously using both hands well.

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 Curls Their Toes
Toe curling is very common in babies and is usually caused by the plantar grasp reflex, which is a normal newborn reflex that causes toes to curl when the sole of the foot is touched. This reflex typically fades by 9-12 months. Occasional toe curling during standing or walking is also normal as babies figure out their balance. Persistent, tight toe curling past 12 months may warrant a mention to your pediatrician.
My Baby Favors One Leg
Babies should use both legs roughly equally when kicking, crawling, and eventually walking. If your baby consistently favors one leg or seems to avoid using the other, it is worth having your pediatrician take a look. The cause is often something simple and treatable, like a minor hip or muscle issue, but early evaluation helps ensure the best outcome.
My Baby Gets Hiccups a Lot
Hiccups are extremely common in babies, especially newborns, and are almost always completely harmless. They happen because your baby's diaphragm is still developing and gets a little jumpy when their tiny stomach fills up or air gets swallowed. Most babies outgrow frequent hiccupping by 6-9 months.
My Baby Has Jerky Movements
Newborns and young babies often have jerky, uncoordinated movements because their nervous systems are still developing. What looks like random flailing is actually your baby learning how their body works. These movements typically become smoother and more controlled by 3-4 months as motor skills mature.
Baby Not Bearing Weight on Arms
Bearing weight on the arms is a gradual skill that develops during the first 6 months. Babies first prop up on their forearms around 2 to 4 months, then progress to pushing up on extended arms by 5 to 6 months. Regular tummy time is the best way to build this strength, even if your baby protests at first.
