There are a lot of developmental milestones to watch for in your child as he gets into his preschool years, says Ari Brown, M.D. author of Toddler 411 (Windsor Peak, 2015). But all of the screentime kids are given today has been associated with poorer developmental test scores. That's why it's important for parents to take time each day to work with their little one on achieving basic milestones.
