Do full-face helmets make sense for young kids?

Specialist MTB subreddits suggest full-face helmets are worth considering for kids riding trails, pump tracks, or BMX, where face-plant risk is real. For sidewalk riding, scooters, and balance bikes, mainstream reviewers say a well-fitted half-shell is plenty. Parents on r/MTB note that lightweight convertible full-face options are easier to keep on small kids than heavy adult-style designs.
