Your baby is officially deep into the 3–4 month stage—no longer a sleepy newborn, but a little explorer in the making.
These weeks are full of small but exciting milestones. You’ll notice more curiosity, more movement, and more sweet attempts at interacting with the world (and you!).
What’s Happening with Your Baby in Weeks 14–15?
Hands are the new best friends. They’ll stare at them, bring them to their mouth, and even try to grab toys.
Better hand-eye coordination. They’re starting to reach intentionally, not just by accident.
Social smiles + first giggles. Your baby may laugh out loud for the first time—pure joy!
More neck strength. Tummy time is less of a struggle—they might push up on their forearms.
Turning toward sounds. If you call their name or make a noise, they may look toward you.
They’re more awake and aware—meaning you’ll have longer, happier play sessions.
Feeding & Sleep
Feeding:
Breastfeeding sessions are now shorter and more efficient.
Bottle-fed babies may take 4–6 ounces per feed.
Babies at this stage are less likely to cluster feed as much as before.
Sleep:
Some babies now sleep 6–8 hours at night, others still wake every 3–4 hours (both are normal!).
Daytime naps might shift toward 3 naps per day with more predictable awake times (~2 hours).
If you’re starting to see a pattern, that’s great—but it’s also okay if you’re not there yet.
Playtime Ideas
At this age, play is all about simple interaction:
Soft rattles & grasp toys. They’ll try to hold and shake them.
Mirror time. Babies love looking at their reflection.
Talking back-and-forth. When they coo, respond—it’s the start of communication.
Tummy time with rewards. Put a favorite toy just out of reach to encourage movement.
These little activities help build motor skills and strengthen your bond.
What You Might Notice
Drooling! It’s not always teething—babies this age just drool more as they explore their mouths.
More awake personality. You’ll see more smiles, more curious looks, and even some frustration when they can’t grab what they want.
Easier soothing. Babies often become calmer after 3 months—they’re used to life outside the womb.
A Gentle Reminder
Your baby is slowly becoming a little person who recognizes you, seeks you out, and loves interacting with you.
These weeks can feel easier than the early newborn haze—soak in the giggles, the little milestones, and those wide-eyed curious looks.
You’re doing so well.
What’s Coming Next?
Weeks 16–18 will bring more movement, maybe some rolling attempts, and a huge developmental leap in awareness. After that, we’ll start talking about getting ready for solids, how poop changes with new foods, and what to watch for with allergies.
