Milestone Snapshot: 0-6 Months
Communication, feeding, and social milestones for the first 6 months of life.
Speech & Sounds
In the first six months, your baby is learning to use their voice. They progress from reflexive crying to purposeful cooing and vocal play. These early sounds are the building blocks of speech.
- Birth-2 months: cries to communicate needs; different cries for hunger, pain, and discomfort
- 2-3 months: begins cooing — soft vowel sounds like 'ooo' and 'aah'
- 3-4 months: vocal play begins — squealing, growling, blowing raspberries
- 4-6 months: babbling begins with consonant-vowel combinations ('ba,' 'da,' 'ma')
- Laughs out loud by 3-4 months
- Experiments with volume — yells, whispers, makes loud and soft sounds
Language & Understanding
Even before your baby says their first word, they are building receptive language skills. They are learning to recognize voices, respond to their name, and understand the rhythm and melody of language.
- Recognizes parent's voice from birth
- Startles to loud sounds and calms to familiar voices
- Begins to respond to their name by 4-6 months
- Turns head toward sounds and voices
- Recognizes familiar words like 'mama,' 'dada,' and 'bottle' in context by 6 months
- Responds differently to happy vs. angry tones of voice
Social Communication
Social communication starts from birth. Your baby is learning to connect with you through eye contact, smiling, and turn-taking vocalizations. These early social exchanges are the foundation for future conversation.
- Makes eye contact during feeding and face-to-face interaction
- Social smile emerges by 6-8 weeks
- Takes vocal turns: you talk, baby coos, you respond, baby coos again
- Shows excitement when seeing familiar people
- Reaches toward people and objects of interest
- Imitates facial expressions (tongue protrusion, mouth opening) by 2-3 months
Feeding Skills
Feeding development in the first six months is primarily about breast or bottle feeding. Oral-motor skills for feeding are closely connected to skills needed for speech development.
- Rooting reflex helps baby find the nipple
- Coordinates suck-swallow-breathe pattern for feeding
- Gradually develops more efficient and faster feeding
- May begin showing interest in solid foods by 4-6 months (watching you eat, reaching for food)
- Introduction of purees typically begins around 4-6 months per pediatrician guidance
Red Flags
While all babies develop at their own pace, certain signs suggest a baby may benefit from early evaluation. Trust your instincts — you know your baby best.
- No smiling or social engagement by 3 months
- Does not startle or respond to loud sounds
- Does not make eye contact during feeding or interaction
- Very quiet — no cooing, squealing, or vocal play by 4-5 months
- Does not turn toward sounds by 5-6 months
- Stiff or floppy body tone affecting feeding or interaction
Important
If your baby does not respond to loud sounds or seems not to hear you, request a hearing screening immediately. Early hearing loss can significantly impact speech and language development.
What You Can Do
The most important thing you can do for your baby's communication development is to interact with them. Talk, sing, read, and respond to their cues. You are your baby's first and most important communication partner.
- Talk to your baby throughout the day — narrate what you are doing
- Respond to their coos and sounds as if they are talking to you
- Sing songs and nursery rhymes
- Read board books with high-contrast pictures
- Make face-to-face time a priority (tummy time, feeding, diaper changes)
- Imitate your baby's sounds — this teaches them that communication is a two-way exchange
