This activity is brilliant for all ages, easy to throw together at short notice and gives them hours of fun. My 8month old has just as much fun as my toddler tipping, scooping and spreading it between his fingers.
I have a tuff tray that I lay down on my kitchen floor. Then I tip in a bag of rice and throw in some containers from the recycling box and different sized spoons. You could also use a small blow up paddling pool or a washing up bowl.
Brilliant for rainy days.
