The Natividad family brings their 18-month-old toddler for a well-child visit. The toddler, named Sofia, is the youngest of three siblings. She was born full-term via normal spontaneous vaginal delivery and has been meeting her developmental milestones. During the assessment, the nurse observes that Sofia is able to walk independently, holding onto furniture for support. The parents express concerns about Sofia’s walking progress and whether she is developing normally.
