Calm, balanced information on the topics parents ask us about most.

Gentle guidance

When Might It Be Helpful to Seek Professional Advice?

Children develop at their own pace. These are gentle signs that a short check-in with a professional could give peace of mind or open up early support. Nothing here is a diagnosis — just things worth noticing.

Limited or No Eye Contact After 18 Months

Worth a chat

Your child rarely looks at you during play, feeding, or when called by name.

Why it matters

Eye contact is one of the earliest ways children build connection and learn from us. Consistent reduction in eye contact can sometimes signal that a child would benefit from extra support with social communication.

When to monitor

If your child sometimes makes eye contact but is shy in new settings.

When to seek professional support

If eye contact is consistently very limited across home, family, and other settings — a chat with a paediatrician or speech-language therapist can offer reassurance or early support.

No Single Words by 18 Months

Worth a chat

Your child isn’t using even 1–2 clear words (like ‘mama’, ‘dada’ or ‘ball’) by 18 months.

Why it matters

First words are an important communication milestone. Early language support is often very effective — and you don't need to wait.

When to monitor

If your child babbles a lot, uses gestures, and understands many things being said to them.

When to seek professional support

If there are no words by 18 months — or your child also doesn’t respond to their name, point, or imitate — consider speaking with a speech-language therapist.

Not Walking by 18 Months

Worth a chat

Your child isn’t walking independently by 18 months.

Why it matters

Most children walk between 9–16 months, but some take a little longer. Persistent delay can sometimes relate to muscle tone, coordination, or motor planning.

When to monitor

If your child is pulling to stand, cruising, and trying to walk.

When to seek professional support

If your child isn’t bearing weight on their legs or hasn’t taken any independent steps by 18 months, mention it at the next health check.

Persistent Toe Walking After Age 3

Monitor gently

Your child walks on tiptoes most of the time after their third birthday.

Why it matters

Occasional tiptoe walking is common in toddlers. Persistent toe walking can sometimes relate to tight calf muscles, sensory differences, or coordination.

When to monitor

If your child can walk flat-footed when reminded.

When to seek professional support

If toe walking is constant, one leg seems tighter, or your child can’t walk flat-footed at all — a physiotherapist or paediatrician can advise.

Loss of Skills (Regression)

Seek soon

Your child loses skills they previously had — words, gestures, or social engagement.

Why it matters

Brief regressions during big changes (new sibling, illness, starting nursery) are common. Persistent loss of skills is worth discussing soon.

When to monitor

If a regression resolves within a few weeks after a stressful event.

When to seek professional support

If your child loses skills and doesn’t regain them within a few weeks, please contact your GP or paediatrician.

Extreme Difficulty with Daily Routines

Monitor gently

Mealtimes, bedtime, or transitions cause daily, intense distress beyond typical for age.

Why it matters

All children struggle with some routines. When daily life is consistently very hard, your child (and family) may benefit from support around regulation, sensory needs, or anxiety.

When to monitor

If distress is short and your child recovers with comfort.

When to seek professional support

If daily routines feel impossible, an occupational therapist or psychologist can help — this is what we're here for.

Limited Pretend Play by Age 3

Worth a chat

Your child doesn’t use objects symbolically (eg, pretending a banana is a phone) or engage in any pretend play by age 3.

Why it matters

Pretend play is a sign of growing imagination, language, and social understanding. Its absence sometimes signals a need for support.

When to monitor

If your child enjoys other types of play (cause-effect, building) and is starting to show interest in imitation.

When to seek professional support

If pretend play is consistently absent and other social-communication concerns are present, speak with a paediatrician.

Strong Reactions to Everyday Sounds or Textures

Monitor gently

Your child is overwhelmed by everyday sounds (hand dryers, vacuums) or refuses many textures.

Why it matters

Many children are sensitive to sensory input. When sensitivities affect daily life — eating, sleeping, getting dressed — an occupational therapist can help.

When to monitor

If your child manages with some adjustments and recovery time.

When to seek professional support

If sensitivities are disrupting daily life, sleep, or eating, an OT assessment can give helpful strategies.

Difficulty Following Simple Instructions by Age 3

Worth a chat

Your child struggles to follow simple one-step instructions like ‘give me the cup’.

Why it matters

Following instructions involves listening, language understanding, and attention. Difficulty here can sometimes signal hearing, language, or processing differences.

When to monitor

If your child follows instructions in familiar routines but struggles with new ones.

When to seek professional support

If your child doesn’t follow instructions even in familiar contexts, check hearing first, then consider a speech-language assessment.

Persistent Difficulty Making Friends (Age 5+)

Monitor gently

Your child struggles to form or keep friendships, finds group play overwhelming, or feels excluded.

Why it matters

Friendships matter for confidence and well-being. Some children need a little extra support to learn the social skills that come naturally to others.

When to monitor

If your child has 1–2 close friends and is generally happy.

When to seek professional support

If your child consistently feels alone, anxious about social settings, or struggles even with familiar peers, a school counsellor or psychologist can support.

You are the expert on your child

If your gut tells you something is off, that matters. Reaching out for an assessment is a confident, caring act — not a sign of failure. Many parents who seek help end up reassured everything is fine.

Build the foundations

Daily habits that nurture healthy development

Small daily choices have the biggest long-term impact on your child’s growth.

Foundation

Sleep

Quality sleep helps your child learn, regulate emotions, and grow. Aim for consistent bedtimes and wake times.

  • Keep bedtime consistent (within 30 minutes) every day.
  • Wind down with a calming routine: bath, story, snuggle.
  • Reduce screens 1 hour before bed.
  • Keep the room dark, cool, and quiet.
Daily fuel

Nutrition

Children thrive with variety, regular mealtimes, and a peaceful atmosphere at the table.

  • Offer balanced meals with protein, veg, healthy fats.
  • Avoid food battles — offer choices, not pressure.
  • Include children in cooking when possible.
  • Eat together when you can; conversation supports digestion.
Brain & body

Outdoor Play

Outdoor play boosts physical health, attention, and well-being — even 20 minutes a day helps.

  • Aim for 60+ minutes of outdoor play most days.
  • Vary the terrain — grass, sand, hills.
  • Embrace mess — mud, water, leaves.
  • Bring play outside when possible: snacks, books, art.
Language & connection

Reading Together

Reading together builds vocabulary, attention, and emotional connection. Make it a daily ritual.

  • Read at the same time each day, even briefly.
  • Let your child choose books.
  • Use voices and pause for predictions.
  • Re-read favourites — repetition deepens understanding.
Active body

Movement

Frequent movement supports muscle strength, coordination, and brain development.

  • Encourage running, jumping, climbing daily.
  • Try animal walks at home — fun and strengthening.
  • Sign up for varied sports rather than specialising early.
  • Walk or cycle to school when possible.
Whole-body input

Sensory Experiences

Rich sensory experiences help children regulate and learn about their bodies.

  • Offer messy play — sand, water, dough, paint.
  • Include movement: spinning, swinging, climbing.
  • Vary textures in clothing and toys.
  • Build deep-pressure activities into your day (squeezes, hugs).
Friendships

Social Interaction

Time with peers and adults helps children learn empathy, turn-taking, and conversation.

  • Arrange small playdates regularly.
  • Model social language: ‘Can I play?’
  • Role-play tricky moments through pretend play.
  • Engage with extended family when possible.
Secure base

Emotional Connection

A few minutes of focused, child-led attention each day builds lifelong well-being.

  • Schedule 10–15 minutes of one-on-one time daily.
  • Let your child lead — follow their interests.
  • Name and validate feelings.
  • Repair after conflict: ‘I’m sorry I shouted.’
Predictability

Routine

Predictable routines help children feel safe, focus better, and learn self-regulation.

  • Keep wake, meal, and bedtimes consistent.
  • Use visual routines for younger children.
  • Prepare for transitions: ‘5 more minutes…’
  • Build flexibility within structure.
Balanced use

Limit Screen Time

Screens have their place, but too much can affect sleep, attention, and language.

  • Avoid screens under 18 months (except video calls).
  • Co-watch with your child to extend learning.
  • Set clear limits and predictable times.
  • Keep meals and bedrooms screen-free.

How we built this

Grounded in developmental science

Our milestones are drawn from peer-reviewed developmental research and globally-recognised references including the CDC’s Developmental Milestones, the American Academy of Pediatrics, the World Health Organization’s Motor Development Study, and the Bayley Scales of Infant and Toddler Development. Every entry has been reviewed by our team of pediatric occupational therapists and speech-language pathologists.

We blend evidence with the lived experience of working with thousands of children and families. We deliberately use warm, accessible language because we believe trustworthy information should never feel cold or clinical.

Milestone ages reflect when most children acquire a skill — but every child is on their own timeline. The ranges are wide and overlap. A child reaching a milestone a few months earlier or later than another is almost always within typical development.
