Getting out of the house with a baby in tow is no easy feat. But your tot is becoming more social and you’re probably desperate for some grown-up conversation (even if it’s about spit-up or sleep deprivation). At this fun stage, little explorers are busy discovering their world and “talking” through smiles, giggles, squeals and babbles. You’re also probably becoming more familiar with your baby’s cries and facial expressions—you two have your own little language.

Sensory activities for 3-month-old babies
This month, your baby is more awake and alert during the day (which hopefully means longer stretches of sleep at night). Here’s what else you need to know.
Ready to explore
Your tot is spending a lot of time exploring: touching, grabbing, looking… and putting things in their mouth. Those are just various ways they get information about their world! Offer your little one crinkly toys and rattles they can hold onto and safely explore with their hands and their mouths.
Back and forth
Your little one is learning about the back-and-forth of things or how things work. If they smile at you, you smile back. If they shake a rattle, it makes a noise. Keeping this sensory game going helps lay the foundation for cause and effect down the line.
Sing-song games
Baby now gets excited by you and others, especially when they talk and smile. Playing games like pat-a-cake, and songs with coordinating gestures like Itsy-Bitsy Spider and others can be a fun way to introduce more social communication. Positive attention from (like talking, singing, smiling, saying how much you love them) helps them feel good about themselves.

Developmental activities for 3-month-old babies
There are lots of interactive things you can do to encourage your baby’s newfound social skills and developmental milestones.
Chatterbox
You might notice your baby attempting to talk by babbling sounds like “ooh” and “ah” then trying p, m and b sounds. Keep up the chit-chat during the day, which encourages them to try out and make more sounds of their own.
Point and name
From wiggling those tiny toes to making a fist, your baby is figuring out all the ways their body works. Start building their vocabulary by pointing to their body parts and naming them, and then helping them move them around: “See this? That’s your elbow! Look how it bends.”

Next-level tummy time
Is your baby ready to level up on tummy time? They may now be able to push up onto their arms from a tummy-down position. Encourage them to keep building up that strength by keeping a toy nearby that’s *just* out of reach. Will they push up to grab it?

Things to do with a 3-month-old
Child development psychologist Dr. Holly Ruhl has week-by-week tips for the coming month.
Week 1
Craving adult interaction? Invite a few mamas and babies for a play date. Swap advice on feeding, naps and balancing the needs of baby, partner and (of course) yourself. Or just chuckle at babies’ attempts at social interaction. Smiling, gesturing or even laughing with pals is an enjoyable way to meet baby’s inherent need for social belonging.
Week 2
If your cutie seems antsy for more mobility, encourage baby to roll from front to back. During baby’s tummy time (aim for 20 minutes daily now—but it doesn’t have to be all in one session!), place a toy on the ground nearby to coax a rollover. If that doesn’t sway your tot, let baby experience the new sensation by gently placing baby’s elbow and arm under their chest and rolling baby in that arm’s direction onto the back.
Week 3
Time outside with your babe can provide bonding opportunities and promote physical and mental health. Get some fresh air with a daily walk in the stroller or babywearing carrier. On your jaunts, keep conversation flowing and focus on labeling a new outside object each day. “Motorcycle Monday,” “Tree Tuesday” or “Sky Saturday,” anyone?
Week 4
The foundations for understanding cause and effect begin early in infancy. Grasping cause and effect with daily experiments is a precursor to later mathematic and scientific reasoning. This week, enhance baby’s understanding of causality by helping those tiny fingers flip light switches on and off, shake a rattle to make noise and drop Rubber Ducky in the tub to make a splash!
