Child development follows predictable patterns, but every child develops at their own pace. Understanding typical milestones helps you support your child's growth and know when to seek help.
Key Principles of Development
- Sequential: Skills build on each other. Babies sit before they walk.
- Individual: Wide ranges are normal. Some babies walk at 9 months, others at 15 months.
- Multifaceted: Physical, cognitive, social-emotional development all happen simultaneously.
- Influenced: Genetics, environment, and experiences all shape development.
When to Discuss Concerns with Your Pediatrician
- Not meeting multiple milestones for their age
- Losing skills they once had (regression beyond normal sleep regressions)
- Not responding to sounds, sights, or social interaction
- Extreme differences from siblings at same age (keeping in mind all kids are different)
Remember: Milestone charts show ranges, not deadlines. "Most children by age X" means some will do it earlier and some later—both normal. Trust your instincts and talk to your doctor if something feels off.
