At The Vine Preschool, we expose our children to paint very early. We start with footprints for babies as early as 4 months (only for special occasions) then from 6 months and up we start hand prints. By the time they can run (very soon after they start walking) we put a paintbrush in their hand.
Sure, they grab the brush at the bristles and get paint all over their hands but how else will they learn if they don’t have the opportunities?
No, not all toddlers will have such as great grasp of the paintbrush but their grasp wouldn’t be like this had she not had some previous exposure.
