Red Flags: When to See a Doctor
Important: Developmental ranges are wide. A single missed milestone is rarely cause for alarm. But patterns - Or multiple flags at the same check - Warrant prompt review with your paediatrician or polyclinic.

In Singapore, Early Intervention Programme for Infants and Children (EIPIC) and KKH Development & Behavioural Paediatrics provide assessments. Early referral - Ideally before age 3 - Significantly improves outcomes. Plot your baby's weight and height with our growth chart calculator to track physical development alongside milestones.
Frequently Asked Questions
Walking typically occurs between 9 and 15 months - With some babies perfectly healthy at 16–17 months. If your baby is cruising along furniture, standing briefly, and otherwise developing well, a brief wait-and-watch approach is fine. Mention it at the next polyclinic visit.
Yes. Some babies go straight from sitting to cruising to walking. Crawling is not a required milestone; it just strengthens core and coordination. If your baby is moving purposefully across the floor (any method), they're doing great.
Around 4 months, sleep cycles mature - Babies start cycling through lighter stages like adults do. This causes more night wakings. It's a developmental leap, not a regression in skills. Our <a href='/baby/sleep/' class='text-primary font-semibold hover:underline'>Baby Sleep Guide</a> covers how to handle it.
Key benchmarks: 1 word by 12m, 10 words by 15m, 50 words and 2-word phrases by 24m. If your child misses these by 2–3 months, ask for a referral to a speech-language therapist (SLT). In Singapore, SLTs are available at polyclinics and KKH.
Use corrected age (chronological age minus weeks premature) for the first 2 years. A baby born 8 weeks early who is 6 months old has a corrected age of 4 months - Compare against 4-month milestones. Most premature babies 'catch up' by age 2–3.
Leaps are periods of rapid brain development - Often accompanied by fussiness, disrupted sleep, and clinginess. They typically precede a new burst of skills. The Wonder Weeks framework identifies 10 major leaps in the first 20 months.
