My Baby Still Mouths Objects After 12 Months
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.
Thousands of parents search for this exact thing. You are not alone.
By Age
What to expect by age
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.
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.
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.
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 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).

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.
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.
