What these numbers mean

Starts ~wk 52

The average age babies first begin showing early signs of this skill. Before this, it's simply too early — there's nothing to worry about.

Median wk 70

The midpoint age: half of babies have reached this milestone by here, half a little later. It's a typical target, not a deadline.

Std dev ±5 wk

How spread out the timing is. About two-thirds of babies achieve it within one standard deviation of the median (the shaded band, wk 65–75). Wide bands mean a normal range of variation.

Flag wk 88

A gentle check-in point. If your baby hasn't shown this by around here, it can be worth mentioning to your pediatrician — most often it's still perfectly fine, just later.

About this milestone

The toddler holds a thick crayon or marker in a fist or palm grasp and makes voluntary marks on paper. This indicates emerging wrist control, shoulder-arm coordination, and visual-motor integration. It is the fundamental foundation for writing and drawing.

What to try & how to support
  • 1. Provide thick, easy-to-grip triangular crayons or egg-shaped chalk designed for a toddler's hand.
  • 2. Sit next to the toddler and draw lines or circles, encouraging them to copy your physical arm movements.
  • 3. Let them draw using finger paints or shaving cream on a tray to build arm-and-hand coordination.
What to avoid & gentle reminders
  • 1. Avoid correcting their hand grip to a 'pencil grip'; a palm-down fist grasp is developmentally normal and necessary at this age.
  • 2. Do not use thin, easily breakable crayons that can break and cause frustration.
  • 3. Avoid using markers or paints that are not labeled as non-toxic and washable.

Every milestone, beautifully remembered.
