Singapore Parents’ Guide to Developmental Milestones: 0-3 Years Month-by-Month Checklist
You find yourself watching your baby a little more carefully than you let on. Comparing. Wondering.
Maybe even Googling at 11pm while everyone else is asleep. Is this normal? Am I missing something?
If that’s where you are right now — you’re not alone, and you’re not overreacting.
Developmental milestones exist to give parents a framework, not a finish line. Every child blooms in their own time. But knowing what to look for — and what deserves a closer look — is one of the most powerful things you can do for your child in those early years.
What Are Developmental Milestones — and Why
Do They Matter?
Developmental milestones are a set of skills or behaviours that most children can do by a certain age. They’re not a rigid test — they’re a map drawn from decades of research across thousands of children, refined by organisations like the US Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and locally by KK Women’s and Children’s Hospital (KKH) and the National University Hospital (NUH).

In Singapore, our children are assessed at well-child visits using structured developmental screening tools — including the Ages and Stages Questionnaire (ASQ-3 and ASQ:SE-2) and Singapore’s own HealthHub developmental screening guidelines. These tools help identify children who may benefit from early intervention — the earlier, the better.
The Four Domains of Child Development

When therapists and developmental paediatricians observe a child, they look across four interconnected domains. A delay in one area can affect others, which is why early and holistic support matters so much.
| Domain | What It Covers | Examples |
|---|---|---|
| 🏃 Gross Motor | Large body movements, balance, coordination | Rolling, sitting, walking, running |
| ✋ Fine Motor | Hand and finger control, eye-hand coordination | Grasping, pinching, stacking, drawing |
| 🗣️ Communication & Language | Receptive understanding and expressive speaking language | Babbling, first words, following instructions, sentences |
| 🧠 Cognitive & Social-Emotional | Thinking, problem-solving, emotional regulation, play, and connection | Object permanence, imitation, pretend play, eye contact |
Milestones at a Glance: 0–6 Months

These first six months are a whirlwind of firsts — first smile, first laugh, first time they track your face across the room. Your baby is taking in the world at breathtaking speed.
Milestones at a Glance: 7–12 Months

This is the age of curiosity and cause-and-effect. Your baby is starting to understand that they can make things happen — drop the spoon, you pick it up. That’s not naughtiness. That’s science.
| Age | Language & Social | Motor & Cognition |
|---|---|---|
| 7–9 Months | Babbles consonant sounds (ba, da, ma); responds to own name; understands “no” | Sits independently; transfers objects hand to hand; begins to crawl or commando-crawl |
| 10–12 Months (1 Year) | Uses “mama/dada” with intent; waves bye-bye; points to objects of interest; plays peek-a-boo | Pulls to stand; cruises along furniture; uses pincer grasp (thumb + index finger); puts objects in containers |
Milestones at a Glance: 13–24 Months

Welcome to the toddler years — possibly the most intense and most beautiful season of early childhood. Words start appearing. Walking becomes running. And opinions? Very much present.
Milestones at a Glance: 25–36 Months
By the time your child turns three, many parents start comparing more — with cousins, with classmates, with children at the playground. This is also the stage where developmental differences can become more visible in group settings.
| Age | Language & Communication | Social & Cognitive | Motor Skills |
|---|---|---|---|
| 24–30 Months (2.5 Years) |
2–3 word phrases; about 200+ words by 30 months; strangers can understand ~50% of speech | Parallel play transitions to interactive play; begins turn-taking; shows empathy | Runs confidently; kicks a ball; turns pages one at a time; stacks 6+ blocks |
| 30–36 Months (3 Years) |
3–4 word sentences; uses pronouns (I, me, you); asks “what” and “where” questions; strangers understand ~75% | Pretend play becomes rich and narrative; plays co-operatively; follows 3-step instructions; understands turn-taking | Jumps with both feet; pedals a tricycle; draws circles; uses scissors with help |

Developmental Red Flags: When to Stop Watching and Start Acting

Paediatricians and developmental specialists often say: “Wait and see” has an expiry date. If you notice any of the following, don’t wait for the next well-child visit — bring it up with your doctor or request a referral for assessment.
| By This Age | Red Flag (Seek Assessment If…) | Domain |
|---|---|---|
| 2 months | Does not smile socially or respond to faces | Social-Emotional |
| 4 months | Does not coo or make sounds; does not follow objects with eyes | Communication / Vision |
| 6 months | Does not laugh or squeal; does not reach for objects | Social / Fine Motor |
| 9 months | Does not respond to name; no babbling; no back-and-forth vocal play | Communication / Social |
| 12 months | No babbling; no gestures (waving, pointing); not pulling to stand | Communication / Motor |
| 16 months | No single meaningful words | Language |
| 18 months | Not using 6–10 words; does not point to share interest; limited pretend play | Language / Social |
| 24 months | No two-word spontaneous phrases; not understood by family 50% of the time | Language |
| Any Age | Loss of skills previously acquired (regression) | All domains — urgent |

What Are Your Next Steps If You’re Concerned?

Here’s the thing about developmental concerns: your instinct as a parent is data. You know your child better than anyone else in the room.
If something doesn’t feel right — a quiet nagging feeling, a gap you’ve noticed, a comparison that won’t leave your mind — that is worth taking seriously.
Every unpolished gem contains brilliance waiting to be revealed. Sometimes all it takes is the right support — at the right time — to begin to bring it out.
