Have a go at making your own Magic Rainbow Milk. Kids of all ages will love it! Magic Rainbow Milk is cheap, quick and easy to set up and if you do it outside (highly recommended!), theres not too much mess to clean up afterwards.
Interactive zip sensory boards or busy boards are really easy to make and great for developing your toddlers fine motor skills. Zip sensory boards are hands-on and engaging, and a great learning through play and sensory activity. All you need are some old zips of different colours and sizes, stiff card or an old cardboard box and glue.
