Physical Development at 3 Months
By 3 months, babies usually have better control over their head and neck. During tummy time, many babies can lift their head and chest using their arms. This helps strengthen muscles needed for later skills such as rolling and sitting.
Other physical milestones at this age may include:
- Kicking legs and waving arms with more control
- Opening and closing hands more easily
- Bringing hands together or to the mouth
- Reaching toward toys or faces
These movements show improving motor skills and muscle coordination. Regular tummy time and safe floor play support physical growth at this stage.
Cognitive and Sensory Development
Cognitive development at 3 months is focused on learning through sight, sound, and touch. Babies become more alert and curious about their surroundings.
At this age, babies may:
- Follow moving objects with their eyes
- Look closely at faces and bright toys
- React to sounds, voices, and music
- Explore objects by touching or mouthing them
These behaviors help build early thinking skills and awareness. Babies begin to understand cause and effect, such as shaking a toy to make a sound.

Social and Emotional Development
Social development becomes more noticeable around three months. Babies start responding more clearly to familiar people and voices.
Common emotional and social milestones include:
- Smiling at caregivers
- Making eye contact
- Turning toward familiar sounds
- Showing excitement through movement or sounds
These reactions help strengthen emotional bonding and attachment. Babies also begin to express comfort and discomfort more clearly.
Language and Communication Development
Although babies are not talking yet, language development begins early. At three months, babies often make sounds to communicate.
- Cooing or gurgling sounds
- Babbling during interaction
- Responding with sounds when spoken to
Talking, singing, and reading to babies at this age helps build early communication skills and supports future language development.
Ways to Support Development at 3 Months
Simple daily activities can encourage healthy growth:
- Talk and read to your baby often
- Provide daily tummy time while supervised
- Offer safe toys with different textures
- Respond to your baby’s sounds and expressions
- Use gentle touch and cuddles
These activities help support physical, emotional, and cognitive development in a natural way.
When to Seek Advice
Every baby develops differently, but professional advice may be helpful if a 3-month-old baby:
- Does not smile or react to faces
- Does not respond to loud sounds
- Has very stiff or very floppy movements
- Keeps fists tightly closed most of the time
- Has difficulty feeding
A doctor or child health nurse can provide guidance and reassurance.
