Behavioral Development: Understanding Your Child’s Behavior

 

By 18 months, most toddlers can point to at least six body parts when asked, a key sign of developing cognitive and language skills.

What You Need to Know

  • Around 12-18 months, toddlers typically begin to show independence, often leading to ‘no’ phases or testing boundaries.
  • By 24 months, a child’s vocabulary can expand significantly, often reaching 150-300 words, according to WHO guidelines.
  • Gross motor skills advance rapidly between 12-24 months, with most toddlers walking independently and starting to run by 18 months.
  • Fine motor skills also develop, with many 18-24 month olds able to stack 4-6 blocks or turn pages in a book.
  • Socially, toddlers start engaging in parallel play around 18 months, playing alongside other children rather than directly with them.
  • Emotional regulation is a developing skill; tantrums are a common expression of frustration when children lack the words to communicate their needs.

The Indian Context: What Research Actually Says

Applying kajal to the baby’s eyes

Region: Pan-India | Verdict: Not evidence-based; observe for any signs of irritation.

No scientific evidence supports this practice for behavioral development. Potential risk of infection or irritation.

Chanting mantras or playing devotional music

Region: Pan-India | Verdict: Can contribute to a soothing environment; focus on the calming effect.

Calming music can positively influence mood and reduce stress in both children and adults, promoting a peaceful atmosphere.

Giving a small amount of tulsi (holy basil) leaves

Region: Pan-India | Verdict: Generally safe in small quantities; focus on its potential health benefits.

Tulsi has antioxidant and antimicrobial properties. Small amounts can be part of a healthy diet, but consult for quantities.

Community play and elder involvement

Region: Pan-India (especially in joint families) | Verdict: Highly beneficial for social and emotional development; encourages learning through observation and participation.

Exposure to diverse social interactions aids in developing empathy, communication, and problem-solving skills.

Common Myths — Busted

Myth: Tantrums mean the child is spoiled or misbehaving intentionally.
Truth: Tantrums are a normal part of development for 1-2 year olds, stemming from an inability to communicate big emotions like frustration or tiredness. By 2 years, children have limited impulse control, making these outbursts common.
Myth: A child who is shy or quiet is not developing socially.
Truth: Temperament varies greatly. Some toddlers are naturally more introverted. Social development includes observing and interacting at their own pace, not just being outgoing. By 18 months, parallel play is a key social milestone.
Myth: Encouraging independence too early will make a child disobedient.
Truth: Fostering age-appropriate independence (like choosing between two outfits) actually builds confidence and cooperation. Research shows toddlers aged 18-24 months who have opportunities for self-directed play show better problem-solving skills.
Paediatrician’s tip:
Reassurance: It’s completely normal for your 18-month-old to have several tantrums a week as they learn to express their big feelings.

When to See Your Paediatrician

  • No babbling or gesturing by 18 months.
  • Loss of previously acquired speech or social skills at any point.
  • Inability to walk by 18 months.
  • Lack of eye contact or showing little interest in social interaction by 12-18 months.

Parents Also Ask

Why is my 18 month old suddenly so clingy?

It’s common for toddlers around 18 months to experience separation anxiety or increased clinginess. This is often linked to their developing sense of self and understanding that you are a separate person. It’s a sign of a secure attachment, and usually peaks around 18-24 months, gradually improving as they gain confidence.

How to stop my 2 year old from hitting?

Hitting is often a sign of frustration or an inability to communicate needs at 2 years old. Instead of punishment, focus on teaching alternatives. Say firmly, ‘No hitting. Use your words.’ Redirect them to a toy or activity and acknowledge their feelings: ‘You’re angry because…’. Consistent modeling and positive reinforcement are key.

My 1 year old is not talking much, should I worry?

At 12 months, a baby typically uses 1-2 words consistently. By 18 months, the average is around 10-20 words, and by 24 months, it can be 50-200 words. If your child is not babbling, gesturing, or using any words by 18 months, it’s worth discussing with a healthcare provider.
