Trẻ sơ sinh 3 tháng học được gì

Sleeping and eating patterns should become more predictable now. You may notice your three-month-old discovering new ways to communicate with you and discover the world … touching, feeling and grabbing everything within reach!

– Recognize Mommy, and be interested in other faces
– Know if something is familiar to her
– Be able to support himself on elbows and raise his chest while on his tummy

How your 3-month-old might play now

    • He recognizes Mommy and is interested in others’ faces
    • She knows if something is familiar
    • Lying on his tummy, he can support himself on his elbows and raise his chest
    • She turns her head toward a sound and watches you as you speak
    • When toys are placed in his hand, he can grasp them and wave them around
    • She can swipe at an object but does not reach for it
Infant play gyms

Help your baby learn more:

    • Demonstrate activities your baby can’t reach yet—playing music or making something rattle or move.
    • Help your baby learn the connection between actions and reactions. Put baby’s hand or foot within reach of the dangling toys. From there, it’s bound to happen: baby’s hand or foot will connect and activate a fun response from the toy!
    • Encourage your child to explore by pointing out colorful activities and describing features. To build memory skills, switch the position of dangling toys from time to time; your baby is likely to notice the change.

Rattles and teethers

Help your baby learn more:

    • Shake it. Place a rattle in baby’s hand and gently shake it. Babies at this age are just beginning to have control over grasping—they can hold on and let go on purpose—so your baby will probably be interested in grabbing, shaking and dropping a rattle.
    • Hear that? Help baby exercise coordination skills by holding a toy in front, shaking it, and letting him reach for it. Put the rattle in baby’s hand, shake it and say, “Hear that sound? You did that!” Emphasizing the reward will make him want to try again.
    • Hand to hand. Choose a rattle that’s big enough to let baby hold on with both hands. Place it in baby’s hand; she’ll grab on with one hand, then the other, and then let go. This action will develop into the skill of being able to pass an object from hand to hand.

Help your baby learn more:

    • Music, please. Extend the benefits offered by a mobile’s music by playing music for baby at other times of the day and in different settings.
    • Sing or hum along. You’ll find that as you do, your baby becomes more vocal too.
    • What do you see? Try looking at the mobile from baby’s point of view. Change its position once in a while, or change your baby’s position so she gets a new view.
    • Make the connection. Right from the start, your baby will listen to and respond to your voice. Use this connection to point things out about the mobile—the colors, the movement, the characters that dangle from it.


Help your baby learn more:

    • Calm down. Help your baby learn to self-regulate—to stop crying and calm down. A soother with gentle sounds, music and sights helps baby understand when it’s time to wind down and go to sleep.
    • See that? Point out the motion and lights to help baby focus on them.
    • So peaceful. Switch through the sound settings until you find one that’s especially soothing to you and baby, then take a few minutes for yourself: listening to the soothing sounds as baby drifts off can be a peaceful time for you, too.
Playard toys

Help your baby learn more:

    • Colors and high-contrast patterns are a great way to stimulate your baby’s visual sense. Point out the colors and name the animals; even though your baby won’t understand the meaning yet, she’ll learn that she can switch her focus, too.
    • Did you hear that? If a toy plays sounds, take advantage of this opportunity to stimulate your baby’s sense of hearing. Take baby’s hands in yours and gently clap them together to the music. Make expressive faces as you playfully sing along or imitate the sounds.

Hats Off

out of 3 vote(s)Your baby is just getting used to recognizing faces, when you introduce the Hats Off game! Your baby won’t be fooled for long, but he’ll enjoy the fun of taking off the hat and putting it back on again.

Try to include a baseball cap, a knit cap, a funny hat, a firefighter’s hat, a clown hat, a bowler, a beret, a pair of earmuffs, or a fancy, feathery hat. (Don’t include masks in your play. They tend to scare babies at this young age.)

Open and Close

out of 2 vote(s)For several months after your baby is born, she has a reflex to grasp objects in her palm, but she has trouble letting go. Here’s a game to help her gain further control of her hands and her grasp reflex.


  • Medium-size toys easily grasped in your baby’s hands, such as rattles, stuffed animals, teething rings, blocks, and so on

  • While your baby’s hands are free, sing the following song as you open, shut, then clap your baby’s hands.

Open, Close Them

Open, close them, open, close them,
Give a little clap!
Open, close them, open close them,
Put them in your lap!

Play Puppet

out of 1 vote(s)As your baby’s vision improves, he can see objects more clearly at greater distances. To work on his focusing and tracking skills, keep a Play Puppet “handy” for feeding, changing, or play time.


  • Clean white sock
  • Permanent felt-tip markers


  • Buy a pair of white socks, large enough to fit over your hands.

  • Place your baby in your lap, on the changing table, or in his infant seat.
  • Slip one puppet onto your hand and entertain your baby with songs, rhymes, or simple conversation. Slip the second puppet onto your other hand for two-handed fun.

  • Seat your baby on your knee, facing you, and hold her arms for support.

Humpty Dumpty sat on a wall,
Humpty Dumpty had a great fall.
All the king’s horses and all the king’s men,
Couldn’t put Humpty together again.

Home again, home again, jiggety-jog.

  • Turkey skewer

  • Baby bathtub or regular bathtub


  • Use a turkey skewer to poke holes on the bottom and sides of the plastic bottle, making holes about one inch apart.

Tummy Talk
