Milestone Mondays!- 12-15 months

Keeping with the template from my first Milestone Mondays,  I gathered this info from a site I brought up in a previous postCDC’s Act Early Campaign, as well as 2 tests/guidelines I use when assessing developmental delays- Peabody Developmental Motor Scales, Gesell Developmental Schedules.

Now that your child or patient has started to move independently while on the floor, around 12 months they begin to become mobile in standing and will likely start to walk independently as well.


Gross Motor

12 months-

  • Can crawl up stairs
  • Gets to a sitting position without help from the crawling position
  • Pulls up to stand, walks holding on to furniture (“cruising”)
  • Walks while holding onto 1 or 2 hands
  • May take a few steps without holding onto anything and walk from object to object
  • May stand alone for a few seconds

15 months-

  • No longer creeps (crawling on hands and knees), only walks, woohoo!
  • Can stand up from the floor without pulling to stand at furniture
  • Can squat while playing with a toy plopping on the floor
  • Can climb into an adult chair
  • Begins to walk quickly
  • Can crawl down stairs
  • Begins to fling a ball in standing and walk into a ball to kick it
  • Can walk up stairs while holding onto your hands

Fine Motor

12 months-

  • Now has a pincer grasp (can grab objects between thumb and index finger)
  • Releases a ball with a slight cast
  • Can help turn pages in a book

15 months-

  • Can stack 2-3 cubes
  • Releases ball with a good cast
  • Can insert shapes into proper shape slot with minimal assistance


12 months-

  • Is shy or nervous with strangers
  • Cries when mom or dad leaves
  • Has favorite things and people
  • Shows fear in some situations
  • Hands you a book when he wants to hear a story
  • Repeats sounds or actions to get attention
  • Puts out arm or leg to help with dressing
  • Plays games such as “peek-a-boo” and “pat-a-cake”
  • Begins cooperative ball play with others (such as sitting and rolling a ball back and forth)

15 months-

  • Begins to hug dolls/animals
  • Begins to offer toy to mirrors
  • Begins to point for what they want
  • Begins to try to feed themselves
  • Tries to pull you to show you something

Language/ Communication

12 months-

  • Responds to simple spoken requests
  • Uses simple gestures, like shaking head “no” or waving “bye-bye”
  • Makes sounds with changes in tone (sounds more like speech)
  • Says “mama” and “dada” and exclamations like “uh-oh!”
  • Tries to say words you say
  • Usually has about 4 words to their vocabulary

15 months-

  • Usually has about 15 words to their vocabulary
  • Understands what you mean when you ask them to get an object from another room 
  • Can usually point to 1 body part when asked
  • Begins to follow directions when asked to throw a ball a certain way (throw ball to me)

Cognitive (Learning, thinking, problem-solving)

12-15 months-

  • Explores things in different ways, like shaking, banging, throwing
  • Finds hidden things easily
  • Looks at the right picture or thing when it’s named
  • Copies gestures
  • Starts to use things correctly; for example, drinks from a cup, brushes hair
  • Bangs two things together
  • Puts things in a container, takes things out of a container
  • Lets things go without help
  • Pokes with index (pointer) finger
  • Follows simple directions like “pick up the toy”


By the end of 12 months…

Act early by talking to your child’s doctor if your child:

  •  Doesn’t crawl
  • Can’t stand when supported
  • Doesn’t search for things that she sees you hide
  • Doesn’t say single words like “mama” or “dada”
  • Doesn’t learn gestures like waving or shaking head
  • Doesn’t point to things
  • Loses skills he / she once had

The bolded ones are important to discuss with your doctor!

The CDC has added another section to their site titled: If You’re Concerned,  I will follow up this post tomorrow with a post containing all the info on that page, but it is a great resource, so please check out their site by clicking the above link!
