Your baby's physical development is unique, and concerns about my toddler has no fear of heights, here is what you need to know.
The short answer
Some lack of safety awareness is normal in toddlers, as the ability to assess risk develops gradually between ages 1-4. However, complete absence of appropriate fear responses, especially combined with other developmental differences, may warrant discussion with your pediatrician. Most toddlers need constant supervision around heights regardless of their fear response.
Key takeaways
- Some lack of safety awareness is normal in toddlers, as the ability to assess risk develops gradually between ages 1-4. However, complete absence of appropriate fear responses, especially combined with other developmental differences, may warrant discussion with your pediatrician. Most toddlers need constant supervision around heights regardless of their fear response.
- Usually normal when: Your toddler is under 2 and lacks fear in most situations.
- Call your doctor if: Your child has had repeated injuries due to lack of safety awareness.
- 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, NIH guidelines, some lack of safety awareness is normal in toddlers, as the ability to assess risk develops gradually between ages 1-4. However, complete absence of appropriate fear responses, especially combined with other developmental differences, may warrant discussion with your pediatrician. Most toddlers need constant supervision around heights regardless of their fear response. At 12-18 months, very limited safety awareness is normal at this age. Your toddler is focused on exploring and has not yet developed the cognitive ability to understand danger. This is why constant supervision is essential. Lack of fear at this age is developmentally appropriate. It is generally considered normal when your toddler is under 2 and lacks fear in most situations. However, you should contact your pediatrician promptly if your child has had repeated injuries due to lack of safety awareness.
Normal vs. Concerning
By Age
What to expect by age
12-18 months
Very limited safety awareness is normal at this age. Your toddler is focused on exploring and has not yet developed the cognitive ability to understand danger. This is why constant supervision is essential. Lack of fear at this age is developmentally appropriate.
18-24 months
Some fear of heights and edges should begin to develop. Your toddler may start to hesitate at edges or look to you for reassurance. If your toddler shows absolutely zero caution in dangerous situations, note this for your pediatrician.
2-3 years
Risk awareness continues developing. Your child should show some caution around heights and dangerous situations. If your child has absolutely no sense of danger, runs toward edges without hesitation, and cannot learn from falls, discuss this with your pediatrician.
3-4 years
Most children have developing risk awareness by now. If your child continues to show no fear in dangerous situations and this is accompanied by other impulsive behaviors, evaluation may be helpful.
What to Tell Your Pediatrician
- Describe when you first noticed my toddler has no fear of heights 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 2 with absolutely no sense of danger or caution.
- Mention if your child repeatedly puts themselves in dangerous situations.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your toddler is under 2 and lacks fear in most situations.

What You Can Do at Home
- Keep track of when you notice my toddler has no fear of heights — noting the time of day, duration, and any triggers can help your pediatrician.

- While monitoring at home, seek immediate care if your child has had repeated injuries due to lack of safety awareness.
Related Conditions
My Toddler Climbs on Everything
Climbing is a normal and important physical milestone for toddlers. Most toddlers go through an intense climbing phase between 12-30 months as they develop gross motor skills, spatial awareness, and body confidence. While exhausting for parents, climbing is a healthy sign of physical development. Focus on making climbing safe rather than preventing it entirely.
My Toddler Is Afraid of Playground Equipment
Some wariness of playground equipment is normal for toddlers, especially with new or large equipment. However, extreme fear of all movement experiences (slides, swings, climbing) may indicate gravitational insecurity, a sensory processing difference where the child feels unsafe when their feet leave the ground. An occupational therapist can help if this significantly limits your child's play.

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.
