Baby milestone FAQs
- What baby milestones should I track in the first year?
- Key milestones include social smiling, holding the head steady, rolling over, sitting without support, responding to their name, babbling, crawling, pulling to stand, and first words — usually emerging across the first 12 months. Ranges vary between healthy babies.
- When should my baby reach each milestone?
- Milestones are typical ranges, not fixed deadlines. The month-by-month guide shows the usual timing, but healthy babies vary. If your baby is well outside the range for several milestones, mention it to your paediatrician.
- Is the baby milestone tracker free?
- Yes. The month-by-month milestone guides are free to read, and a free ParentVibes account lets you log your baby's milestones and save memories.
- Should I worry if my baby is a little behind?
- Not usually — babies develop at their own pace and often catch up quickly. Trust your instincts, and if you're concerned about several milestones or a regression, speak with your paediatrician, who can properly assess development.
