During which age range will a baby begin to bring their hands to their mouth?

Your baby will grow and change rapidly during their first year. Every child is different, and your little one will reach development milestones at their own pace. There are some typical age ranges, though, when some of the most exciting advances happen. Watch -- and enjoy -- as your baby moves into each new phase.

1 to 3 Months

Around 1 month after your baby is born, they'll still have jerky arm and leg movements and not much neck control. They'll probably keep their hands in a fist shape, and their eyes may cross from time to time.

But there are also some new skills that are starting to show up. They can probably:

  • Bring their hands near their face
  • Pay attention to people's faces over other objects
  • Focus their eyes on things 8-12 inches away
  • Turn their head from side to side while lying on their back
  • Turn toward sounds and voices they recognize
  • Smiles when you talk to or smile at them
  • Reacts to loud noises 

By the time your baby is 3 months old, you'll notice some other things going on. They may:

  • Try to grab for and hold on to objects
  • Put their hand in their mouth
  • Stretch and kick while lying on their back
  • Push down against a surface when their feet are placed on it
  • Calm themselves occasionally by finding a hand or finger to suck on
  • Coo or gurgle using mostly vowel sounds
  • Focus on objects farther away than 12 inches
  • Raise their head off the floor or push up their torso while lying on their stomach

 

4 to 6 Months

As your baby closes in on the halfway point of their first year, they are no longer a newborn. Their movements will have more purpose, and their vision and speech skills will grow. They'll probably be able to:

  • Smile at people
  • Copy sounds they hear
  • Use different cries to express different feelings (hunger, pain)
  • Follow an object with their eyes
  • Copy expressions on others' faces
  • Reach for toys with one hand
  • Roll from tummy to back and maintain control of head
  • Makes sounds back when you talk to them
  • Pushes up on their elbows or forearms when on their tummy

At the halfway point of their first year, they should be able to:

  • Realize when someone is unfamiliar
  • Look at themselves with interest in the mirror
  • Play with other people, especially their mom and dad
  • Start stringing more than one sound together when they babble
  • Respond to their name
  • Bring objects to their mouth
  • Reach for toys and grab them
  • Pass a toy from one hand to another
  • Laughs
  • Closes lips when they don't weant food

By 6 months, some babies can also:

  • Roll over in both directions
  • Start sitting without support
  • Hold their weight on their legs when they stand
  • Rock back and forth on hands and knees

7 to 9 Months

Your baby gets steadier as they grow. From 7 to 9 months, some master sitting up on their own and using their hands to pick up and move things. Others even walk by 9 months. Babies usually have full color vision by 7 months.

Typically, at the end of 9 months, your baby may be able to:

  • Cling to you when someone unfamiliar is around
  • Prefer certain toys over others
  • Understand the word "no"
  • Recognizes their name
  • Play games like peekaboo
  • Reach for a toy that's far away
  • Put things in their mouth
  • Shows several facial expressions to show emotion
  • Makes a lot of different sounds such as "mamamama" of "babababa"
  • Sit on their own
  • Pull up to standing
  • Stand while holding on to something
  • Crawl
  • Lifts arms to be picked up
  • Looks for objects that they dropped like a toy or spoon.
  • Bangs things together

10-12 Months

As your baby approaches 1 year, they can explore more of the world than ever before. They have learned new ways to communicate with you and others, and is getting more mobile every day. They can likely:

  • Bring you a toy to play with or a book to read
  • Recognize when you're leaving and get upset about it
  • Get your attention with noises or movement
  • "Help" dress themselves by putting arms and legs through clothes
  • Use gestures to say things ("no" and "goodbye")
  • Say a few simple words like "Mama" or "uh-oh"
  • Mimic words you say
  • Find an object behind your back
  • Clap their hands together and wave
  • Point
  • Follow simple directions
  • Drink from a cup
  • Use their thumb and forefinger to pick up small objects, including food that they put in their mouth

There's a wide range of skills when it comes to sitting, crawling, and standing at this age. It's normal for a 1-year-old not to walk, but some do. On average, most 1-year-olds can:

  • Get into a sitting position alone
  • Pull up to standing
  • "Cruise" (move while holding on to furniture or other support)
  • Stand alone
  • Take a few steps

When it comes to reaching milestones, remember: Your baby is in charge. They'll cross the goal line when they are good and ready. If you have concerns about how your child is developing, check with your pediatrician. Some of the changes you may see as each month goes by:

When can babies put their hands in their mouth?

During the first few months of life, babies persistently attempt to bring their hands to their mouths but have not developed the strength or skills to keep them there. By 4 months, however, babies can put their hands in their mouths and keep them there (if they choose).

What does it mean when babies bring hands in their mouth?

In the newborn months, a baby who sucks their hand may be trying to tell you they're hungry. Think about it: Every time they suck on a bottle or nipple, they get food! It's a natural sucking instinct, similar to rooting, meant to clue you in that it's time for another feeding.
