Unfolding Case Study #1-1 Maddie
Maddie is a 6-month-old infant whose birth weight was 7 pounds 5 ounces, head circumference
was 16 inches, and her length was 21 inches. She presents to the clinic with her parents for a
well child visit.
Exercise 1-1: Calculation
You weigh Maddie at her visit and document her weight as 15 pounds, head circumfer- ence as 16 inches,
and length as 25 inches. You plot her measurements on the chart and determine her percentiles for height
and weight. What percentile is she in terms of weight and length?

Exercise 1-2: Fill-in
How would you interpret these findings in relation to her percentile and other female infants of the same
age? _______________________________________________________________________________
eResource 1-2: In order to plot Maddie’s weight go to:
■ The Centers for Disease Control and Prevention’s (CDC)’s website
(www.cdc.gov.growthcharts) and download the Birth to 36 Months: Length for Age and Weight
for Age profiles. Plot the appropriate weight and height to determine the percentile each
parameter falls within.

, You also listen to Maddie’s heart and lungs and assess Maddie’s gross motor devel-
opment during her visit.
Exercise 1-3: Multiple-choice question
Which findings would indicate that Maddie has met gross motor age-appropriate milestones?
A. Maddie is able to pull herself to a stand.
B. Maddie can sit alone without support.
C. Maddie can roll from her back to her abdomen. D. Maddie can grasp a rattle with her fingers.
Maddie’s father asks you for suggestions about appropriate play for her.
Exercise 1-4: Select all that apply
Based on an understanding of growth and development, and safety, select all toys that would
meet Maddie’s needs.
❑ Brightly colored latex balloons ❑ Push–pull toys
❑ Teething toys
❑ Books with bright pictures
❑ Brightly colored soft toys ❑ Stacking blocks
eResource 1-3: To reinforce your teaching regarding normal growth and development,
you provide the following resources from Baby World:
§ Reading materials regarding normal 6 month development: goo.gl/T2pTr7
§ Videos:
■ Baby on the Move: Sitting: goo.gl/PlKvkz
■ Baby on the Move: Crawling: goo.gl/uFhJ9o
Maddie’s parents are very attentive to your teaching and you provide them with
literature about age-appropriate activity. You also review with them home safety for a 6-
month-old. Their next visit is established in another 3 months when Maddie will be 9
months old. At that time you will prepare them for safety issues that involve a child that
is more mobile.
