2 Month Baby Milestones: First Smiles, First Coos, and Real Connection

2 Month Baby Milestones: First Smiles, First Coos, and Real Connection

Month two is when your baby stops being a mysterious screaming potato and starts being a tiny person who SMILES at you. It's the reward you've been waiting for.

The second month marks a significant shift. Your baby is more awake, more alert, and—finally—giving you something back for all those sleepless nights. Here's what to expect.

The Big Milestone: Social Smiling

Somewhere between 6-8 weeks, it happens: a real smile. Not gas. Not a reflex. An actual smile in response to YOU.

How to Tell It's Real:

• Happens when you're interacting (not random)
• Involves the whole face (especially the eyes)
• Repeatable—smile at baby, baby smiles back
• Makes your heart explode (this is the key diagnostic)

Motor Skills: Getting Stronger

What Most 2-Month-Olds Can Do:

• Lift head briefly during tummy time (45 degrees)
• Turn head side to side when lying on back
• Smoother movements (less jerky than newborn phase)
• Bring hands to mouth (beginning of self-soothing)
• Unclenched fists (hands relaxing more)
• Briefly hold lightweight object if placed in hand

What They're Working On:

• Holding head steady when supported upright
• Following objects with eyes
• Pushing up on arms during tummy time

Communication: Cooing Begins

The Sounds of Two Months:

• Cooing: Vowel sounds like "ooh," "aah," "ooo"
• Gurgles: Happy throat sounds
• Variety in crying: Different cries for different needs
• Responding to sounds: Startles, turns toward noise

Early "Conversations":

• You talk, baby pauses and listens
• Baby coos, you respond
• Taking turns (the foundation of conversation)
• This back-and-forth builds language development

Vision: Seeing the World

What Baby Can See Now:

Focus range	8-15 inches (expanding from newborn)
Color vision	Developing—prefers bold contrasts
Face recognition	Knows you! Studies faces intently
Tracking	Follows moving objects with eyes

What Baby Loves to Look At:

• Your face (the favorite view)
• High-contrast patterns (black and white still popular)
• Moving objects
• Lights and shadows
• Other babies (in person or mirrors)

Sleep at 2 Months

What's Normal:

• Total sleep: 14-17 hours per day
• Longest stretch: 4-6 hours at night (for lucky parents)
• Still waking: 2-4 times per night is normal
• Naps: 4-6 per day, inconsistent timing

Sleep Tips:

• Differentiate day and night (bright/active vs. dark/quiet)
• Watch for sleepy cues (yawning, eye rubbing, fussiness)
• Begin a simple bedtime routine
• Swaddling often still helpful

Feeding at 2 Months

What to Expect:

• Frequency: 6-8 feedings per day (every 3-4 hours)
• Amount: 4-5 oz per bottle, or effective nursing sessions
• Night feeds: Still 1-3 per night
• Duration: Faster, more efficient than newborn phase

Signs of Good Feeding:

• Steady weight gain
• 6+ wet diapers daily
• Satisfied between feeds
• Alert and active when awake

When to Contact Your Pediatrician

Every baby develops differently, but reach out if:

• No social smiling by 2 months
• Doesn't follow objects with eyes
• Doesn't respond to loud sounds
• Doesn't bring hands to mouth
• Can't hold head up briefly during tummy time
• Seems very stiff or very floppy
• One eye turns in or out consistently
