BP Child Fatty by George Triantafyllakos is a free childlike handwritten font with thick, wobbly strokes and a loose, marker-drawn feel. The letters look rounded and slightly lumpy, with uneven curves and casual joins that give the whole design an honest, school-notebook energy rather than a neat script finish.
That makes it a natural fit for kids' book covers, playful packaging, classroom posters, party invitations, and short branding where a free font needs to feel informal and homemade. It also works well for title cards, simple logos, and brief headlines, because the chunky, bouncy lettering carries the mood fast without feeling polished or strict.
