We love our Easiyo maker and although some may think of nothing worse than making a mess from head to toe with your food, it is a great learning experience for babies. I made up a batch of Mason's yogurt http://www.goldenglow.com.au/product/EasiYo-Bio-Life-Organic-Unsweetened/378/103
Covered his highchair tray with foil so the white yogurt would be more visible and create a nice shiny picture. Placed some dobs of fresh homemade yogurt and put him in to explore.
Was cautious at first rubbing it through his fingers then squishing it in his hands
