A really simple and easy game to keep under 5s busy if you need some time with your older child.
Counting Hide and Seek
Send your child on a hide and seek treasure hunt! Use numbers that your child is confident with so they don’t need much adult interaction. Ask them to go and find 1 pair of socks and bring it back then when they have check, praise them and send them off for another amount of items eg 6 cuddly toys etc etc
