Milestones Your Baby at 6 Months

Milestones matter. How your baby plays, learns, speaks, acts, and moves offers important clues about your baby’s development. Check the milestones your baby has reached by 6 months. Talk with your baby’s doctor at every well visit about the milestones your baby has reached and what you can expect in the months ahead.

An infant with light skin, curly brown hair and brown eyes is holding a baby toy in its mouth while lying on its stomach in a diaper.

Most 6-month-olds can do these things:

Social/Emotional Milestones

  • Knows familiar people
  • Likes to look at himself in a mirror
  • Laughs

Cognitive Milestones

(learning, thinking, problem-solving)

  • Puts things in her mouth to explore them
  • Reaches to grab a toy he wants
  • Closes lips to show she doesn’t want more food

Language/Communication Milestones

  • Takes turns making sounds with you
  • Blows “raspberries” (sticks tongue out and blows)
  • Makes squealing noises

Movement/Physical Development Milestones

  • Rolls from tummy to back
  • Pushes up with straight arms when on tummy
  • Leans on hands to support himself when sitting
  • What are some things you and your baby do together?
  • What are some things your baby likes to do?
  • Is there anything your baby does or does not do that concerns you?
  • Has your baby lost any skills he/she once had?
  • Does your baby have any special healthcare needs or was he/she born prematurely?

You know your baby best. Don’t wait. If your baby is not meeting one or more milestones, has lost skills he or she once had, or you have other concerns, act early – it can make a big difference. Talk with your baby’s doctor, share your concerns, and ask about developmental screening.

If you or the doctor are still concerned:

  • Ask for a referral to a specialist who can evaluate your baby more.
  • Visit Nevada’s Early Intervention Services web page, or call (800) 522-0066 to find out if your baby can get services to help.

As your baby’s first teacher, you can help his or her learning and brain development. Try these simple tips and activities in a safe way. Talk with your baby’s doctor and child care providers if you have questions or for more ideas on how to help your baby’s development.

  • Use “back and forth” play with your baby. When your baby smiles, you smile; when he makes sounds, you copy them. This helps him learn to be social.
  • “Read” to your baby every day by looking at colorful pictures in magazines or books and talk about them. Respond to her when she babbles and “reads” too. For example, if she makes sounds, say “Yes, that’s the doggy!”
  • Point out new things to your baby and name them. For example, when on a walk, point out cars, trees, and animals.
  • Sing to your baby and play music. This will help his brain develop.
  • Limit screen time (TV, tablets, phones, etc.) to video calling with loved ones. Screen time is not recommended for children younger than 2 years of age. Babies learn by talking, playing, and interacting with others.
  • When your baby looks at something, point to it and talk about it.
  • Put your baby on her tummy or back and put toys just out of reach. Encourage her to roll over to reach the toys.
  • Learn to read your baby’s moods. If he’s happy, keep doing what you are doing. If he’s upset, take a break and comfort your baby.
  • Talk with your baby’s doctor about when to start solid foods and what foods are choking risks. Breast milk or formula is still the most important source of “food” for your baby.
  • Learn when your baby is hungry or full. Pointing to foods, opening his mouth to a spoon, or getting excited when seeing food are signs that he is hungry. Others, like pushing food away, closing his mouth, or turning his head away from food tells you that he’s had enough.
  • Help your baby learn she can calm down. Talk softly, hold, rock, or sing to her, or let her suck on her fingers or a pacifier. You may offer a favorite toy or stuffed animal while you hold or rock her.
  • Hold your baby up while she sits. Let her look around and give her toys to look at while she learns to balance herself.
