Your toddler fills a cup and pours it into a bowl. Then they fill the cup again, and pour it again.

Ten minutes later, they're still going.

To us, it's just water moving from one container to another. To a young child, there's a surprising amount to figure out in that small cup.

Why do toddlers love pouring water?

Pouring lets toddlers try something, see what happens, and try it again. Each pour gives them feedback through their hands and eyes, and sometimes through a wet shirt. Repeating it gives them practice in controlling how their hands and arms move.

What your child may be exploring

• Cause and effect: When they tip the cup, the water moves. When they tip it faster, it splashes.
• Hand and arm control: Holding a cup steady, tilting it slowly and stopping at the right moment all take coordination.
• Aiming: Getting water into the bowl instead of onto the floor is a real challenge.
• Early ideas about amount: Full, empty, too much, overflowing. What happens when a big cup is poured into a small one?
• How water feels: It's cool and wet, heavy when the cup is full and light when it's empty.

Why do they repeat it so many times?

Repeating something is one of the main ways young children practise. Each pour is slightly different, so they may be adjusting their grip, speed or angle without you noticing.

Try this at home

You only need two plastic cups, a bowl and a tray or towel underneath. A kitchen sponge makes a fun extra: they can squeeze it and watch the water drip out.

Always stay within arm's reach during water play, even with a small amount of water.

What you might notice

• Does your child pour slowly and carefully, or tip everything out at once?
• Do they prefer the big cup or the small one?
• Do they watch the water closely, or look at your face when it splashes?

There's no right or wrong here. It's simply a chance to see how your child likes to play.

A simple thought

The play that looks the most ordinary is often where children are doing the most experimenting.

And sometimes they just think the splash is funny.
