Babies typically start rolling over between 4 and 6 months old.
Here's a more detailed look:
- Around 4 months: Babies may begin to rock from side to side. This motion is the foundation for rolling over. They might also roll from their tummy to their back.
- Around 6 months: Most babies can roll over in both directions (back to tummy and tummy to back).
Therefore, while the range is between 4 and 6 months, it is important to remember that all babies develop at their own pace.
