There are four stages of drawing and writing that kids go through. The earliest stage starts as young as 15 months old to 2½ years old. That is the random scribbling stage, where you’ll have no idea what they’re trying to draw, but that’s fine. They’re exploring different colors and practicing fine-motor skills. Between the ages of 2 and 3 years old, they go through the controlled scribbling stage. That’s where their drawings start to make a little more sense.
