Your baby's physical development is unique, and concerns about my toddler's jaw alignment seems off, here is what you need to know.
The short answer
Some jaw alignment variations in toddlers are normal and may resolve as the jaw grows and permanent teeth come in. Underbites, overbites, and crossbites in baby teeth do not always predict permanent tooth alignment. A pediatric dentist can monitor jaw growth and determine if early intervention is needed.
Key takeaways
- Some jaw alignment variations in toddlers are normal and may resolve as the jaw grows and permanent teeth come in. Underbites, overbites, and crossbites in baby teeth do not always predict permanent tooth alignment. A pediatric dentist can monitor jaw growth and determine if early intervention is needed.
- Usually normal when: Mild overbite or underbite in baby teeth.
- Call your doctor if: Your child cannot close their mouth properly.
- 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.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP, NIH, CDC guidelines, some jaw alignment variations in toddlers are normal and may resolve as the jaw grows and permanent teeth come in. Underbites, overbites, and crossbites in baby teeth do not always predict permanent tooth alignment. A pediatric dentist can monitor jaw growth and determine if early intervention is needed. At 6-12 months, jaw alignment is difficult to assess with only a few teeth. The jaw is still growing and changing rapidly. No intervention is typically needed at this age. It is generally considered normal when mild overbite or underbite in baby teeth. However, you should contact your pediatrician promptly if your child cannot close their mouth properly.
Normal vs. Concerning
By Age
What to expect by age
6-12 months
Jaw alignment is difficult to assess with only a few teeth. The jaw is still growing and changing rapidly. No intervention is typically needed at this age.
12-24 months
As more teeth come in, alignment patterns become more apparent. Mild overbites and underbites are common and often self-correct. Pacifier and thumb-sucking habits can affect alignment but usually resolve if habits stop by age 3-4.
2-3 years
With a full set of baby teeth, your child's bite pattern is more visible. A pediatric dentist can evaluate alignment at regular dental visits. Crossbites (upper teeth sitting inside lower teeth) may be monitored more closely.
3-5 years
If significant jaw misalignment persists, early orthodontic evaluation may be recommended. Some conditions benefit from early intervention while the jaw is still growing. Your pediatric dentist can refer to an orthodontist if needed.

My Toddler Grinds Their Teeth and It's Causing Wear
Teeth grinding (bruxism) is very common in children, affecting up to 30% of kids under age 5. Most children outgrow it. Mild grinding rarely causes lasting damage to baby teeth. However, if grinding is causing visible wear, pain, or sleep disruption, a pediatric dentist can evaluate and provide guidance.
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.
