When a 3-year-old’s forehead is crunched, it is important to seek medical treatment promptly to remove the scar and perform a non-invasive suture. Methods may include using a soft tissue expander to expand normal skin before repairing the scar, or performing intracutaneous drug injections, scar sanding, and topical medication treatments. Parents should regularly take their children for routine check-ups and treat them according to the doctor’s guidance.
