When to Consult a Professional
If your baby shows persistent delays, early support can make a big difference. Talk to a healthcare provider if your baby:
- Doesn’t smile by 3 months
- Can’t lift head or control movements by 4 months
- Doesn’t babble or respond to sounds by 6–7 months
- Doesn’t sit or crawl by 9–10 months
- Can’t stand or walk by 12 months
Every baby is unique — some develop quickly in certain areas and take more time in others. Still, don’t hesitate to ask questions or get reassurance.
