Play with water!

This was their uncle's not so innocent suggestion.

They were two and four years old, and the eldest struggled with baths and water play in general. 

They had warm water and Duplo.

I did not water proof the room.

I did not expect them to play with this activity.

They played so beautifully.

Until they didn't.

It was successful however. My eldest wasn't scared of the water during this fun activity.

What would I have done differently?

Taken them outside!
