Your baby's physical development is unique, and concerns about still mouths objects after 12 months, here is what you need to know.
The short answer
Some mouthing after 12 months is normal, especially during teething or with new textures. However, if your toddler mouths objects constantly and intensely after 18 months, it may indicate oral sensory seeking behavior. This is often manageable with appropriate sensory strategies and does not necessarily indicate a developmental concern.
Key takeaways
- Some mouthing after 12 months is normal, especially during teething or with new textures. However, if your toddler mouths objects constantly and intensely after 18 months, it may indicate oral sensory seeking behavior. This is often manageable with appropriate sensory strategies and does not necessarily indicate a developmental concern.
- Usually normal when: Your toddler occasionally mouths objects during teething.
- Call your doctor if: Your child has suddenly started mouthing everything after not doing so.
- 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.”

What Parents Should Know
According to AAP, CDC, NIH guidelines, some mouthing after 12 months is normal, especially during teething or with new textures. However, if your toddler mouths objects constantly and intensely after 18 months, it may indicate oral sensory seeking behavior. This is often manageable with appropriate sensory strategies and does not necessarily indicate a developmental concern. At 12-15 months, some mouthing is still very normal at this age, especially during teething (molars come in around 13-19 months). Your toddler should also be exploring objects in other ways - shaking, banging, stacking. As long as mouthing is decreasing and other exploration is increasing, development is on track. It is generally considered normal when your toddler occasionally mouths objects during teething. However, you should contact your pediatrician promptly if your child has suddenly started mouthing everything after not doing so.
Normal vs. Concerning
By Age
What to expect by age
12-15 months
Some mouthing is still very normal at this age, especially during teething (molars come in around 13-19 months). Your toddler should also be exploring objects in other ways - shaking, banging, stacking. As long as mouthing is decreasing and other exploration is increasing, development is on track.
15-18 months
Mouthing should be decreasing. Your toddler may still mouth new or interesting textures occasionally, which is fine. If mouthing is still a primary exploration method, try redirecting to other sensory activities.
18-24 months
Persistent, frequent mouthing at this age is worth discussing with your pediatrician. It may indicate oral sensory seeking or developmental differences. Providing appropriate chew toys and oral sensory input can help redirect the behavior.
2-3 years
Regular mouthing of non-food objects at this age warrants evaluation. An occupational therapist can assess whether there are sensory processing differences and provide strategies. Some children need extra oral sensory input and benefit from chewy tubes or crunchy foods.
What to Tell Your Pediatrician
- Describe when you first noticed still mouths objects after 12 months 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 18 months and frequently mouths non-food objects.
- Mention if mouthing is not decreasing over time.
- 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 occasionally mouths objects during teething.
- Mouthing is decreasing over time and other play is increasing.
- Your toddler mouths new textures briefly then explores in other ways.
- Your child is under 18 months.
- Your child is over 18 months and frequently mouths non-food objects.
- Mouthing is not decreasing over time.
- Your child mouths objects to the exclusion of age-appropriate play.
- Your child has suddenly started mouthing everything after not doing so.
- Your child is ingesting non-food items (pica).
What You Can Do at Home
- Keep track of when you notice still mouths objects after 12 months — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your toddler occasionally mouths objects during teething — this is generally within the range of normal.
- At 12-15 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 child has suddenly started mouthing everything after not doing so.

My Baby Mouths Everything
Mouthing objects is a completely normal and important way for babies to explore the world. Babies use their mouths as sensory organs because the mouth has more nerve endings than the hands. Mouthing peaks around 6-9 months and typically decreases significantly by 12-18 months, though some mouthing is normal well into toddlerhood.
My Toddler Avoids Messy Play
Some toddlers are more sensitive to textures and messy experiences than others. Mild reluctance with new textures is normal. However, extreme avoidance of all messy or tactile play, crying when hands get dirty, or refusing to touch common textures may indicate tactile defensiveness, a form of sensory sensitivity that can benefit from occupational therapy.

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.
