Infant development: Milestones from 10 to 12 months

Medically reviewed by Last updated on Jun 25, 2020.

Your baby is constantly on the move. Nothing makes him or her happier than dropping a spoon from the highchair over and over again. If you aren't stifling the urge to say "No!" chances are you've said it in the last few hours. Welcome to life with a 10- to 12-month-old! At this age, infant development is rapid.

What to expect

From ages 10 to 12 months, your baby is likely to enjoy:

  • Improved motor skills. Most babies this age can sit without help and pull themselves to a standing position. Creeping, crawling and cruising along the furniture will eventually lead to walking. By 12 months, your baby might take his or her first steps without support.
  • Better hand-eye coordination. Most babies this age can feed themselves finger foods, grasping items between the thumb and forefinger. Your baby might delight in banging blocks together, placing objects in a container and taking them out, as well as poking things with his or her index finger.
  • Evolving language. Most babies this age respond to simple verbal requests. Your baby might become skilled at various gestures, such as shaking his or her head no or waving bye-bye. Expect your baby's babbling to take on new inflection and evolve to words such as "dada" and "mama." You might hear certain exclamations, such as "uh-oh!"
  • New cognitive skills. As your baby's understanding of object permanence improves, he or she will be able to easily find hidden objects. Although your leaving the room might lead to crying, your baby will begin to realize that you still exist even when you're out of sight. You might find your baby imitating you by brushing his or her hair, pushing buttons on the remote control or "talking" on the phone.

Promoting your baby's development

Your baby's budding curiosity is bound to keep you on your toes. Keep your baby safe while challenging him or her to learn through play.

  • Create an exploration-safe environment. Move anything that could be poisonous, pose a choking hazard or break into small pieces from your baby's reach. Cover electrical outlets, use stairway gates, and install child locks on doors and cabinets. If you have furniture with sharp edges, pad the corners or remove it from areas where your baby plays. The same goes for lightweight objects your baby might use to pull himself or herself to a standing position, such as plant stands and decorative tables. Anchor bookcases, televisions and their stands to the wall.
  • Snuggle up and read. Set aside time for reading every day — even if it's only a few minutes. At this age, your baby might love books with flaps, textures or activities. Make your reading more interesting by adding facial expressions, sound effects and voices for characters. Store books within easy reach so that your baby can explore them whenever the mood strikes.
  • Keep conversations going. If your baby reaches for a book, ask, "Would you like to read a story?" If he or she points to the cow on the cover, say, "You found the cow! What does a cow say?" Wait for your baby's response and then offer the correct answer. As you're reading the book, get creative. Make up your own stories to fit the pictures. Ask your baby questions about the pictures. Don't limit yourself to yes or no questions.
  • Help your baby handle his or her feelings. Expect episodes of frustration as your baby struggles to make sense and take control of his or her environment. If your baby throws plastic rings out of frustration, calmly pick up the pieces and say, "I can see you're frustrated. Let's figure it out. The big ring goes here. Now you try." For some babies, learning a few words in sign language can be helpful. Teach your baby simple motions for common words, such as milk and blanket.
  • Set limits. Babies don't have a sense of right or wrong. Praise your baby for good choices while steering him or her away from hazardous situations. Use a calm no if your baby hurts others. Explain calmly why the behavior isn't OK, and then redirect your baby's attention.

When something's not right

Your baby might reach some developmental milestones ahead of schedule and lag behind a bit on others. This is normal. It's a good idea, however, to be aware of the signs or symptoms of a problem.

Consult your baby's doctor if you're concerned about your baby's development or your baby:

  • Doesn't crawl or consistently drags one side of the body while crawling
  • Can't stand with help
  • Doesn't use gestures, such as waving or shaking the head
  • Doesn't babble or attempt words such as "mama" or "dada"
  • Doesn't search for objects that are hidden while he or she watches
  • Doesn't point to objects or pictures

Trust your instincts. The earlier a problem is detected, the earlier it can be treated. Then you can look forward to the delights and challenges that lie ahead.
