Make your own snow paint at home with the kids. Such a fun winter activity for toddlers and preschoolers that you can do inside when it's wet and cold. An easy paint recipe you can adapt for all sorts of snow and winter creations.
Kids will have fun making their own garden fairies, especially over summer when plants are in full bloom. Teach them the names of the flowers that you use, discuss the different shades of colour and how plants grow.
