Your baby's physical development is unique, and concerns about delayed hand dominance, here is what you need to know.
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.
Key takeaways
- 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.
- Usually normal when: Your child is under 2 years old and uses both hands equally, switching between them freely.
- Call your doctor if: 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.
- Varies by age — see the age-by-age breakdown below
“Supervised tummy time is recommended daily from the time the baby comes home from the hospital to help prevent flat head syndrome and to strengthen neck and shoulder muscles.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, CDC guidelines, 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. At 6-12 months, 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. It is generally considered normal when your child is under 2 years old and uses both hands equally, switching between them freely. However, you should contact your pediatrician promptly if 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.
Normal vs. Concerning
By Age
What to expect by age
6-12 months
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.
1-2 years
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.
2-3 years
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.
3-5 years
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 to Tell Your Pediatrician
- Describe when you first noticed delayed hand dominance and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if 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.
- Mention if your child seems to avoid using one hand entirely, which may indicate weakness on that side rather than true hand preference delay.
- Bring a list of any questions or observations you want to discuss at the appointment.
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.
What You Can Do at Home
- Keep track of when you notice delayed hand dominance — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your child is under 2 years old and uses both hands equally, switching between them freely — this is generally within the range of normal.
- At 6-12 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Provide plenty of supervised floor time and tummy time to support your baby's physical development.
- While monitoring at home, seek immediate care if 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.

Bottom line
Most cases of delayed hand dominance are normal. Talk to your pediatrician if 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.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.

Should I Use Adjusted Age for My Preemie's Milestones?
Yes — for premature babies, developmental milestones should be assessed using adjusted (corrected) age, not chronological age, until at least 2 years of age. Adjusted age is calculated by subtracting the number of weeks your baby was born early from their actual age. For example, a 6-month-old born 2 months early would have an adjusted age of 4 months, and should be assessed against 4-month milestones. Most pediatricians use adjusted age for developmental assessment through age 2-3, and for growth charts through age 2.
Baby-Proofing a Small Apartment
Baby-proofing a small apartment is absolutely possible and focuses on the same key safety principles as any home: securing furniture to walls, covering outlets, locking cabinets with hazardous materials, and ensuring safe sleep spaces. Small spaces actually have an advantage - there is less area to monitor. Focus on eliminating the most dangerous hazards first: falls, poisoning, choking, and burns.
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.
My Baby Crawls Unevenly
While some variation in crawling patterns is normal, consistently favoring one side or dragging one limb while crawling warrants attention. Babies should use both arms and both legs relatively equally when crawling. Persistent asymmetry could indicate muscle tone differences, hip issues, or neurological concerns that benefit from early evaluation.
