Stock up on art supplies
Always have on hand pencils, paints, crayons, markers, clay, brushes, sponges, paper, etc. For younger children, it's easy to overwhelm them by laying out too many options at once, and they can make a gigantic mess at times! So start by keeping it simple at first and build from there once they get the hang of things.
Display the artwork of all your children
Singling out the “talented” child will cause problems with your other kids' self-esteem or stifle their interest in art. And if you have a child with more artistic talent, teach them to respect the work of others, that art can be approached in many different ways.
Don't "correct" your child’s artwork
Don't adjust/fix anything, or show your child "the right way" to do it. Offer assistance if and when you’re asked, otherwise stay out of it and let them see where their creativity takes them. If your child asks you to, it's okay to work side-by-side on art projects. This is a good way to accompany them without running the show or making something so "perfect" that they'll be frustrated the next time they work on their own. Some of the most creative work comes when things don't go according to plan. So encourage your preschooler to try new things and assure them that it’s fine to get things "wrong." Kids can be timid about their work or resist taking risks because they're afraid they'll fail. Whether your child is a typical preschool scribbler or an emerging artist, they may be sensitive to criticism or eager for praise.
