My Baby Shows an Early Hand Preference
The short answer
True handedness - consistently preferring one hand over the other - should not develop until at least 18 months to 2 years of age, and often not until age 3-4. If your baby strongly favors one hand before 18 months, it may indicate that the other hand or arm is weaker or has decreased coordination, which is worth discussing with your pediatrician.
By Age
What to expect by age
Young babies naturally alternate between hands and should use both sides of their body equally. If you notice your baby consistently keeping one hand fisted while the other hand opens and grasps freely, this is an important observation to share with your pediatrician. It can sometimes indicate a difference in muscle tone between the two sides of the body.
Babies at this age should be reaching, grasping, and transferring objects with both hands, though you might notice a slight preference emerging. It's normal for a baby to use their right hand more often than their left (or vice versa), but they should still be capable of using both hands effectively. If one hand is clearly dominant and the other is rarely used, mention it to your doctor.
Some preference is emerging but your toddler should still use both hands for play, self-feeding, and exploration. If your child almost exclusively uses one hand and avoids using the other, or if the non-preferred hand seems weaker or clumsier, an evaluation is recommended. Early identification of asymmetry leads to better outcomes.
True handedness can begin to emerge after 18 months and is completely normal. The key distinction is: does your child prefer one hand but CAN use the other effectively? If so, that's typical handedness developing. If one hand is significantly weaker or less coordinated, that's different and should be evaluated.
What Should You Do?
When to take action
- Your baby is over 18 months and uses one hand more often but can use both hands well - true handedness is starting to develop naturally.
- Your baby alternates which hand they prefer depending on the activity or which side an object is on.
- Your baby uses both hands together for activities like banging toys, holding a bottle, or clapping.
- Your child reaches with whichever hand is closer to the object rather than always crossing the body to use the same hand.
- Your baby under 12 months consistently reaches with only one hand and rarely uses the other.
- One of your baby's hands seems weaker or clumsier than the other.
- Your baby avoids using one hand during play even when objects are placed on that side.
- You notice that one hand seems tighter or more fisted than the other past 3-4 months of age.
- Your baby used to use both hands equally and has stopped using one - any loss of function requires prompt evaluation.
- One hand is consistently fisted while the other moves freely, especially after 4 months of age - this can indicate neurological differences that benefit from early therapy.
- Your baby has no use of one arm or hand and cannot grasp with it at all.

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.
