Take the Screener

Your child is officially entering grade school, and the things they learn each year are shifting to reflect that. While kids get their first experience with school in preschool and kindergarten, grade school is when they start to see more structure. Spending each school day surrounded by peers also allows their social circles to expand, and while they’ll start by sticking with friends of the same gender, they’ll soon begin to make friends from both. 

Between ages 6 and 12, your child’s language skills continue to develop as their vocabulary expands and they learn how to use their words to express themselves. Your child is also acquiring thinking and reasoning skills at this age, allowing them to work through decisions and better follow your rules.

The following guides, one for each year, will help you see what developmental milestones you can look forward to when your child is between the ages of 6 and 12. 

6-Year-Old Milestones

A 6-year-old’s cognitive abilities are maturing. They can now understand more complex ideas — such as cause-and-effect relationships — along with what is real and what is only imagination. They can also distinguish between past and present and understand that similar things can be grouped together. 

At the same time that your 6-year-old is starting to lose their baby teeth (be prepared for all the gap-toothed grins!), they’re also developing their first molars, so if your child isn’t brushing their teeth consistently, now is a great time to have them start with this responsibility.

Here are more developmental milestones for 6-year-olds:

Speech and Language

  • Learns to express themselves through words
  • Speaks with correct grammar most of the time
  • Can spell their first name
  • Pronounces words correctly
  • Can describe a favorite TV, movie, story, or other activity
  • Reads simple words


  • Learns to write
  • Draws a person with at least 8 parts
  • Likes to run, skip, and jump
  • Can catch a ball
  • Uses safety scissors easily
  • Skips with ease
  • Can write their name
  • Can control their major muscles
  • Has good balance
  • Can write some letters and numbers


  • Starts to understand the feelings of others, but only with the encouragement of their parents and other caregivers
  • May be prone to jealousy with siblings and friends
  • May struggle to process frustrating moments, such as losing a board game or struggling to master a skill

Thinking and Reasoning

  • Starts to grasp the concept of time
  • Can follow a series of at least three commands


  • Starts to understand cause-and-effect relationships
  • Likes to be the “big kid” who is taking care of a younger child
  • Dresses themselves, but may need some help with difficult laces or buttons

  • Wants their parents to play with them, but starts to fulfill more needs with friends and other people they admire, such as teachers
  • Plays with a lot of imagination 
  • Develops a sense of humor — may like simple jokes and funny rhymes and books

6-Year-Old Developmental Red Flags

Reach out to your pediatrician if your 6-year-old struggles with any of the following:

  • Wets the bed
  • Frequent tantrums
  • Tantrums that last longer than a few minutes
  • Sensitivity to different sensations that doesn’t go away with repeated exposure
  • Significant loss of skills
  • Cannot differentiate between real and pretend
  • Does not turn to adults for help or comfort
  • Excessively seeks adult approval and attention
  • Vision problems (e.g., complains about not being able to read signs at a distance, a lack of interest in reading, lots of eye rubbing, squinting, abnormal eye alignment, sensitivity to light)

7-Year-Old Milestones

Now that your child has started to lose their baby teeth, you can expect the tooth fairy to visit about four times a year, and these gaps will then be filled with their permanent teeth.

Your child’s thinking and reasoning skills are also developing. Your 7-year-old can name the days, months, and seasons, and they can also find similarities between two objects. However, their self-esteem may also be fragile during this time, so offer frequent encouragement and support. Their self-criticism is high, so emphasize how much they’ve learned instead of the final product. 

Here’s the developmental checklist for a 7-year-old: 

Speech and Language

  • Tends to talk a lot when in a situation where they are comfortable
  • Is becoming a better reader but may still struggle with sounding out vowels


  • More coordinated in activities using their large muscles, such as climbing or swimming

  • Can throw a ball with accuracy at a target
  • Can catch a ball with one hand
  • Has good balance


  • Becomes more aware of and sensitive to the feelings of others
  • Overcomes some childhood fears but can still be scared of the unknown
  • Reads emotions from facial expressions
  • Has strong emotional reactions
  • Starts to feel guilt and shame
  • Desires to be perfect
  • Is very self-critical

Thinking and Reasoning

  • Has a solid sense of time and understands seasons, seconds, minutes, hours, days, weeks, months, and sometimes years.
  • Can solve simple math problems using objects
  • Considers issues and problems using one factor at a time
  • Can describe points of similarity between two objects
  • Begins understanding that letters represent the sounds that form words
  • Can solve more complex problems
  • Understands the difference between right and wrong


  • Begins to prefer a learning style (e.g., working quietly on their own, hands-on activities)
  • Can tie their own shoe laces
  • May transition from taking a bath to taking a shower


  • Forms friendships, usually with other children of the same gender
  • Plays in larger groups sometimes
  • Draws a person with 12 parts
  • Avoids and withdraws from adults
  • Waits for their turn in activities

7-Year-Old Developmental Red Flags

Since every child develops at their own rate, your 7-year-old may not hit all the milestones listed above. However, let your pediatrician know if you notice any of the following:

  • Does not respond to positive praise and attention
  • Acts sad or nervous much of the time
  • Does not share or take turns with other children
  • Unable to dress self
  • Unable to feed self

8-Year-Old Milestones

At 8 years old, your child’s moral compass is taking over, and they’re starting to understand right and wrong and which things correspond to each category. This is also the stage when your child will start to understand the value of money and may enjoy counting and saving what they have.

12-Year-Old Milestones

It’s the end of your child’s pre-teen years, and by this point, they have likely started to undergo puberty. This means the first period for girls and the development of muscle for boys. However, with puberty, emotions can also quickly shift, and kids may start to show rebelliousness and a desire to argue for no reason. 

Here’s the list of milestones for 12-year-olds:

Speech and Language

  • Communicates easily with others
