Well Child Care, 3-Year-Old


At 3, the child can jump, kick a ball, pedal a tricycle, and alternate feet while going up stairs. The child can unbutton and undress, but may need help dressing. Three-year-olds can wash and dry hands. They are able to copy a circle. They can put toys away with help and do simple chores. The child can brush teeth, but the parents are still responsible for brushing the teeth at this age.


Crying and hitting at times are common, as are quick changes in mood. Three-year-olds may have fear of the unfamiliar. They may want to talk about dreams. They generally separate easily from parents.


The child often imitates parents and is very interested in family activities. They seek approval from adults and constantly test their limits. They share toys occasionally and learn to take turns. The 3-year-old may prefer to play alone and may have imaginary friends. They understand gender differences.


The child at 3 has a better sense of self, knows about 1,000 words and begins to use pronouns like you, me, and he. Speech should be understandable by strangers about 75% of the time. The 3-year-old usually wants to read his or her favorite stories over and over and loves learning rhymes and short songs. The child will know some colors but have a brief attention span.

The majority of 3-year-olds are toilet trained during the day. Only a little over half will remain dry during the night. If your child is having bed-wetting accidents while sleeping, no treatment is necessary.


  • Your child may no longer take naps and may become irritable when he or she does get tired. Do something quiet and restful right before bedtime to help your child settle down after a long day of activity. Most children do best when bedtime is consistent. Encourage your child to sleep in his or her own bed.

  • Nighttime fears are common and the parent may need to reassure the child.


  • Spend some one-on-one time with your child.

  • Allow your child to make choices and try to minimize telling your child "no" to everything.

  • Discipline should be fair and consistent. Time-outs are effective at this age.

  • Warn your child about walking up to unfamiliar dogs, especially when dogs are eating.

  • Children should be protected from sun exposure. You can protect them by dressing them in clothing, hats, and other coverings. Avoid taking your child outdoors during peak sun hours. Sunburns can lead to more serious skin trouble later in life. Make sure that your child always wears sunscreen which protects against UVA and UVB when out in the sun to minimize early sunburning.

  • Know the number for poison control in your area and keep it by the phone.


Your next visit should be when your child is 4 years old.
