He has also recently begun to ride a tricycle. Upon questioning you also find that he is toilet trained and can stack 9 blocks. Upon examination you find that he can copy a circle though he cannot yet copy a triangle or draw stick figures.

He can stack 2 blocks and put the blocks in a cup. He can bring over a book when asked, and he will say “mama” and “dada” to call for his parents, as well as 'book', 'milk', and 'truck'.

A 1-year-old male presents to his pediatrician for a well-child visit. Through a history from the mother and physical examination, the pediatrician learns that the baby babbles non-specifically, takes several steps independently, and picks up his cereal using two fingers. His weight is currently 22 lbs (birth-weight 6 lbs, 9 oz), and his height is 30 inches (birth length 18 inches). Are there any aspects of this child's development that are delayed?

An 8-year-old boy is brought to the physician by his parents because of repeated episodes of “daydreaming.” The mother reports that during these episodes the boy interrupts his current activity and just “stares into space.” She says that he sometimes also smacks his lips. The episodes typically last 1–2 minutes. Over the past 2 months, they have occurred 2–3 times per week. The episodes initially only occurred at school, but last week the patient had one while he was playing baseball with his father. When his father tried to talk to him, he did not seem to listen. After the episode, he was confused for 10 minutes and too tired to play. The patient has been healthy except for an episode of otitis media 1 year ago that was treated with amoxicillin. Vital signs are within normal limits. Physical and neurological examinations show no other abnormalities. Further evaluation of this patient is most likely to show which of the following findings?

A female child presents to her pediatrician for a well child visit. Her mother reports that she is eating well at home and sleeping well throughout the night. She can jump and walk up and down stairs with both feet on each step. In the doctor’s office, the patient builds a six-cube tower and imitates a circle. She seems to have a vocabulary of over 50 words that she uses in two-word sentences. Her mother reports that the patient enjoys playing near other children and sometimes argues over toys with her older brother. On physical exam, she appears well developed and well nourished, and she is following along her growth curves. The child is assessed as developmentally normal. Which of the following is an additional milestone associated with this child’s age?

A 3-year-old boy is brought to the office by his mother because of a large head contusion and altered mental status.
