“My 15-month-old isn’t talking yet — should I be worried?” 

 

It’s completely normal to feel anxious when milestones seem delayed. While some children speak later than others, a lack of spoken words by 15 months can be a sign that your child would benefit from extra support. It doesn’t always mean that something is ‘wrong’, but it could be time to explore early intervention. 

 

At First Bridge Education, we often meet families with similar concerns. We offer personalised, gentle but targeted support that meets your child exactly where they are, whether they’re just starting to babble or showing signs of delay. 

Understanding your child’s early developmental milestones is one of the most powerful ways you can support their learning and wellbeing. In this guide for parents, we break down typical communication, play, and learning milestones for babies and toddlers and explain what to do if you have concerns. We’ll also share tips and insights from our expert team of BCBA’s on how you can support your child at home! 

0–6 Months: The Foundations of Connection

In the first few months, babies are learning to bond with caregivers and respond to the world around them. 

 

Typical milestones: 

  • Turns toward sounds and voices 
  • Begins to smile in response to others 
  • Makes eye contact and watches faces 
  • Cries differently to express different needs 
  • Enjoys early interactions like singing or gentle games 

 

Communication Building Tip from Joey (BCBA – Clinical Supervisor): “Engage in face-to-face play and copy their sounds to support their early communication pathways.” 

6–12 Months: Early Explorers

For babies, this stage is about interaction, imitation, and showing their preferences. 

Typical milestones: 

 

  • Babbles with intent (“ba-ba,” “da-da”) 
  • Looks at what you point to 
  • Reaches or gestures to communicate 
  • Responds to name and simple instructions 
  • Enjoys peek-a-boo and other social games
     

Development Insight from Christine (BCBA – Clinical Supervisor): “Gestures, joint attention, and imitation are early social-communication foundations. Positively reinforce them as often as you can!”  

12–18 Months: First Words and New Worlds

Toddlers begin combining their understanding of language with their growing independence. 

 

Typical milestones: 

  • Uses 5–10 clear words 
  • Follows one-step instructions like “give me the toy” 
  • Uses gestures to request (pointing, waving, lifting arms) 
  • Recognises familiar people and routines 
  • Starts basic pretend play (feeding a doll, brushing hair) 

Encouragement Tip from Georgia (BCBA – Clinical Supervisor): “Narrate daily routines to build vocabulary, for example, “We’re putting on your shoes to go outside!” “ 

18–24 Months: Rapid Communication Growth

Language accelerates, and toddlers become more socially aware. 

 

Typical milestones: 

  • Combines two words (e.g. “more milk”) 
  • Follows two-step instructions 
  • Points to body parts when named 
  • Plays next to other children (parallel play) 
  • Starts showing empathy (e.g. comforting others) 

 

Support Tip from Andreea (BCBA – Clinical Lead): “Offer choices during daily routines to build confidence and motivation for communication, for example “banana or apple?” “ 

24–36 Months: Imagination and Expression

At this age, children begin expressing ideas and navigating social interactions. 

 

Typical milestones: 

  • Uses 200–300 words and short phrases 
  • Follows three-step instructions 
  • Enjoys pretend play with characters and stories 
  • Identifies basic shapes and colours 
  • Uses language to express wants, needs, and feelings
     

Learning Insight from Sharon (BCBA): “Encourage storytelling, questions, and simple ‘why’ answers to build critical thinking. Using visuals like picture cards and role play can support developing these skills, too.” 

36–48 Months: Independent and Inquisitive

Children become increasingly self-directed and social. 

 

Typical milestones: 

  • Holds simple conversations with others 
  • Plays cooperatively with peers 
  • Understands concepts like “same” and “different” 
  • Uses imaginative play with roles and narratives 
  • Asks lots of “what,” “where,” and “why” questions
     

Encouragement Tip from Mikaela (BCBA – School Principal & Clinical Director): “Use open-ended prompts like ‘What do you think will happen next?’ to spark conversation.” 

When to Get Support 

At First Bridge Education, we know that every child develops at their own pace. However, you may want to seek guidance if your child: 

  • Doesn’t babble, gesture, or respond to their name by 12 months 
  • Has fewer than 10 words by 18 months 
  • Struggles with eye contact or joint attention 
  • Shows limited interest in others or play 
  • Displays intense sensitivity to sound, touch, or routine changes
