What these numbers mean
Starts
~wk 17
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 26
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
±3 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 23–29). Wide bands mean a normal range of variation.

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
Promote hand-eye coordination and manual dexterity by encouraging the infant to transfer items between hands.
What to try & how to support
- 1. Provide texture-ridged plastic loops or thin-handled rings that allow a secure grasp from either side.
- 2. Offer a second toy to the hand that is already occupied to encourage the infant to transfer the first object over.
- 3. Model transferring objects between your own hands while keeping direct, engaged eye contact with the infant.
What to avoid & gentle reminders
- 1. Avoid giving tiny objects that present a choking risk if the infant brings them to their mouth.
- 2. Avoid using rigid plastic toys that can hurt the infant's face or gums during coordinated movements.
