Behavior

Teaching Toddlers Gentle Hands and Gentle Touch

Teaching "gentle hands" is one of the most important and most repeated lessons of the toddler years. Young children genuinely do not understand their own strength or that their actions cause pain. Gentle touch must be actively taught and demonstrated hundreds of times. It is a skill that develops gradually through patient, consistent modeling and practice - not through punishment.

Physical

My Toddler Has Severe Knock Knees

Mild knock knees are a normal developmental phase that peaks around age 3-4 and typically resolves by age 7-8. However, severe knock knees (where the distance between ankles is greater than 8-10cm when knees touch), asymmetric knock knees, or knock knees that worsen after age 4 should be evaluated by a pediatric orthopedist.

Speech

Gestalt Language Processing in Toddlers

Gestalt language processing is a style of language learning where children acquire whole phrases or "chunks" before breaking them down into individual words. Instead of learning "want" + "cookie" separately, a gestalt learner memorizes "want a cookie" as a single unit. This is a valid language development path, not a disorder. However, gestalt language learners may need specific support to progress through the stages of breaking down and recombining language.

Sleep

Toddler Keeps Getting Out of Bed

Getting out of bed repeatedly is one of the most common challenges after transitioning to a toddler bed. Your child is testing their exciting new freedom. The most effective approach is calm, consistent, and boring: walk your child back to bed with minimal interaction, tuck them in briefly, and leave. It may take many repetitions, but consistency works.

Behavior

Toddler Gives Up Easily and Will Not Try

Some toddlers give up quickly when faced with challenges. This can be related to temperament, fear of failure, low frustration tolerance, or having been helped too quickly in the past. Persistence is a skill that develops over time with encouragement, appropriate challenges, and a safe environment where mistakes are accepted. It is not a character flaw.

Speech

Toddler Replacing R and L with W and Y

Gliding is a phonological process where R and L sounds are replaced with W or Y, such as "wabbit" for "rabbit" or "yeg" for "leg." This is one of the last phonological processes to resolve, often persisting until age 5 or even 6. Gliding is normal and expected in toddlers and preschoolers, and speech therapy is typically only recommended if it persists past age 5 to 6.

Speech

Toddler's Grammar Errors Not Improving

Grammar errors are a completely normal part of language development in toddlers and preschoolers. Children naturally say things like "I goed" or "him is big" as they learn grammar rules. Most grammar errors resolve by age 4 to 5. If errors persist beyond age 5 or if your child uses very limited grammar for their age, a speech-language evaluation may be helpful.

Physical

Toddler Grinding Teeth While Awake and Asleep

Teeth grinding (bruxism) is very common in babies and toddlers - studies suggest 15-33% of children grind their teeth. Babies often grind their teeth when new teeth come in because the sensation is novel and they are experimenting with their bite. Most children outgrow grinding by age 6 when their permanent teeth start coming in. Grinding is usually harmless and does not require treatment unless it is causing tooth damage, jaw pain, headaches, or significantly disrupting sleep.

Physical

My Toddler Has Leg Pains at Night

Growing pains are common, affecting up to 40% of children, and typically begin between ages 2-4. They cause aching pain in the legs, usually in the evening or at night, and do not cause limping or joint swelling. Massage, warm compresses, and gentle stretching usually help. If your child limps, has joint swelling, or has daytime pain, other causes should be evaluated.

Feeding

My Toddler Is Eating Less and Growing More Slowly

It is completely normal for toddlers to eat less and grow more slowly compared to their first year. Growth rate naturally slows after age 1, and appetite decreases accordingly. Most toddlers gain only about 3-5 pounds between their first and second birthdays compared to 12-15 pounds in the first year. This reduced appetite is called physiologic anorexia of toddlerhood and is a normal developmental phase. As long as your toddler is following their growth curve and has good energy, there is usually no cause for concern.

Physical

My Toddler's Behavior Changes During Growth Spurts

Growth spurts in toddlers can cause temporary behavior changes including increased hunger, extra sleepiness, fussiness, and clinginess. These episodes typically last a few days to a week and are a normal part of development. Growth spurts are less predictable in toddlers than in babies but may occur every few months.

Behavior

Toddler Hair Twirling Habit

Hair twirling is one of the most common self-soothing behaviors in young children and is usually completely harmless. Many toddlers twirl their own hair (or a parent's hair) when tired, falling asleep, nursing, or feeling stressed. It is similar to thumb-sucking or blanket-rubbing as a comfort habit. In the vast majority of cases, children outgrow hair twirling on their own without any intervention needed.

Behavior

Toddler Flaps Hands When Excited

Hand flapping during excitement is very common in toddlers under age 3 and is often a normal way of expressing big emotions that they cannot yet verbalize. It becomes more concerning when it is very frequent, occurs outside of emotional moments, is combined with other repetitive behaviors, and persists past age 3 to 4. Context matters more than the behavior itself.

Physical

My Toddler's Hands Shake During Fine Motor Tasks

Some hand trembling during concentrated fine motor tasks can be normal in toddlers as their nervous system is still maturing. However, persistent or worsening hand tremors, especially those that occur during reaching (intention tremor), should be evaluated by your pediatrician to rule out neurological concerns.

Speech

Toddler's Hearing Seems to Come and Go

Fluctuating hearing in toddlers is most commonly caused by middle ear fluid that comes and goes, often associated with colds, allergies, or ear infections. When fluid is present, hearing is muffled; when it drains, hearing returns to normal. If your child's hearing seems inconsistent, an audiological evaluation can determine whether fluid or another condition is affecting their hearing.

Behavior

Subtle Signs of Autism in Toddlers

Some children have subtle autism features that are easy to miss. They may have adequate language but struggle with the social aspects of conversation. They may play alongside peers but not truly interact. They may have intense interests that seem like typical childhood passions. If you sense something is different about your child's social development even though you cannot pinpoint it, trust your instincts and request an evaluation.

Behavior

Toddler Hitting Baby Sibling

It is very common for toddlers to hit, push, or be rough with a baby sibling. Toddlers have limited impulse control and cannot fully understand that the baby is fragile. This behavior is usually driven by jealousy, frustration, curiosity, or a desire for attention rather than malice. Close supervision, calm redirection, and teaching gentle touch are the most effective strategies.

Behavior

Toddler Hitting or Banging Their Own Head

Head banging and self-hitting are surprisingly common behaviors in babies and toddlers, affecting up to 20% of healthy children. Most head banging is a self-soothing behavior, similar to thumb sucking or rocking, and often occurs at bedtime or during frustration. It typically starts around 6-9 months and peaks between 18-24 months. Most children outgrow head banging by age 3-4. While alarming to witness, children rarely hurt themselves from typical head banging, and it is not usually a sign of a developmental problem.

Behavior

Toddler Hitting Parents

Being hit by your toddler is one of the most upsetting experiences in parenting, but it is also one of the most common and normal behaviors between 12 and 36 months. Toddlers hit the people they feel safest with - usually their parents - because they feel secure enough to express their biggest, most overwhelming emotions. They are not being "bad" or intentionally hurtful. They are showing you that their feelings are too big for their small bodies and limited vocabulary to handle. This behavior improves with consistent, calm responses as language and emotional regulation develop.

Behavior

Toddler Hits When Angry or Frustrated

Hitting is one of the most common toddler behaviors and is developmentally normal between ages 1-3. Your toddler hits because their emotions are bigger than their ability to manage them, and physical expression is their most available tool. Hitting does not mean your child is aggressive or that you are failing as a parent. Respond by calmly stopping the behavior, naming the emotion, and teaching alternatives over many, many repetitions.

Digestive

Toddler Holding in Poop

Stool withholding is very common in toddlers, often triggered by a painful bowel movement that makes them afraid to go again. The resulting cycle - holding leads to harder stool, which leads to more pain, which leads to more holding - can be frustrating but is very treatable. A combination of stool softeners (as recommended by your pediatrician), dietary changes, and a calm, pressure-free approach usually resolves it.

Behavior

Toddler Ignores You When You Speak to Them

Toddlers who seem to ignore you are usually not being deliberately disrespectful. Common reasons include: they are genuinely absorbed in play (young children have difficulty shifting attention), they have learned that you will repeat yourself multiple times before there are consequences, they do not understand the instruction, or they are asserting autonomy. Rarely, consistent non-response could indicate a hearing issue worth checking.

Behavior

Toddler Has an Imaginary Friend

Imaginary friends are a normal and healthy part of childhood development. Research shows that up to 65% of children have an imaginary friend at some point, most commonly between ages 2.5 and 7. Children with imaginary friends often have advanced language skills, greater creativity, better social understanding, and stronger emotional processing. An imaginary friend is a sign of a healthy imagination, not a problem.

Speech

Toddler Repeats Everything You Just Said

Immediate echolalia, where a child repeats what was just said to them, is common in language development between ages 1 and 2.5. It can serve as a language learning strategy, helping children practice sounds and sentence structures. However, persistent echolalia that replaces spontaneous communication beyond age 3 may indicate a language processing difficulty and should be evaluated.
