By the end of their first month, most babies:
- Make jerky, quivering arm movements
- Bring hands near face
- Keep hands in tight fists
- Move head from side to side while lying on stomach
- Focus on objects 8 to 12 inches away
- Prefer human faces over other shapes
- Prefer black-and-white or high-contrast patterns
- Hear very well
- Recognize some sounds, including parents’ voices
Remember this is only a guideline; each child is unique and develops at their own pace.
