What to Expect During Your Baby’s Fourth Month
A Big Leap in Development and Joyful Milestones
Your baby is officially four months old! Can you believe how fast time is flying? At this stage, your little one is blossoming, gaining strength, personality, and awareness of the world around them. The fourth month is often described as a turning point — both for baby’s development and for you as a parent. Here’s what you can expect during this exciting time.
1. Physical Development: Getting Stronger Every Day
This month, your baby is building strength in major ways:
- Neck and head control: Most babies can now hold their heads up steadily and may even push up onto their elbows during tummy time.
- Rolling over: Some babies begin rolling from tummy to back — a thrilling milestone!
- Hand-eye coordination: Your baby will reach out, grab toys, and bring them to their mouth. Everything is a new discovery.
- Kicking and wiggling: Expect lots of movement as their legs grow stronger — it’s great prep for future crawling.
Tip: Keep offering plenty of tummy time — it builds muscles and helps prevent flat spots on the back of the head.
2. Cognitive Growth: The Curiosity Spark
Your baby’s brain is in overdrive! During this month, they begin to:
- Recognize familiar faces and voices more clearly.
- Follow moving objects with improved vision and tracking skills.
- React to cause and effect — like shaking a rattle and hearing the sound.
- Imitate sounds — coos may turn into delightful giggles or attempts at conversation.
Milestone moment: Your baby might start laughing! Don’t be surprised if something random (like a silly face or noise) gets a giggle fit going.
3. Sleep Patterns: Still Evolving
Sleep during the fourth month can be unpredictable. Many babies experience a “4-month sleep regression,” which can mean more frequent night waking.
- Total sleep time is usually 12–16 hours a day.
- Naps become more structured — typically 3 to 4 a day.
- Bedtime routines are more important than ever to help them wind down.
Tip: A soothing bedtime routine (bath, lullaby, soft lights) can signal it’s time for rest and help ease the transition to sleep.
4. Feeding: Hungry for More?
Whether you’re breastfeeding, formula feeding, or both, your baby is likely becoming more efficient at eating.
- Feeding every 3 to 4 hours is common.
- Some babies show signs of readiness for solids — but always consult with your pediatrician before starting.
- Watch for hunger cues like sucking hands, rooting, or fussiness.
Note: The American Academy of Pediatrics generally recommends introducing solids around 6 months.
5. Bonding and Playtime: Emotional Growth Blooms
Your baby is connecting with the world emotionally. Look for:
- Big smiles when you talk to them.
- Excited kicks when they see their favorite toy.
- Loving gazes during snuggles or feeding.
This is also a great time to introduce:
- Mirror play
- Soft music or lullabies
- Books with bold images and high contrast
Activity idea: Try gentle games like peek-a-boo or singing nursery rhymes. Your baby loves your voice more than anything.
6. When to Talk to Your Pediatrician
Every baby develops at their own pace, but check in with your pediatrician if you notice:
- No response to loud sounds or voices
- Poor head control
- Little to no movement or interest in interaction
- Difficulty feeding or gaining weight
Final Thoughts
The fourth month is full of growth, joy, and a few challenges — but it’s a beautiful part of your baby’s journey. Celebrate the milestones, ask for help when needed, and remember: you’re doing a wonderful job.
Cherish every coo, cuddle, and giggle — they’re the memories that last a lifetime.
