How parents say good-bye can determine their toddler or preschooler's reaction. So as tempting as it may be, don't wait for your child to get distracted and then sneak off without a hug and a kiss. For some kids, looking up to find that you've already gone can leave them feeling even more alone. Instead, keep your good-bye short and to the point with a snappy hug, a peck on the cheek, and a "See you soon, buddy!" Even body language can convey that you're just as sad as he is, so stand up straight and smile. It's your way of saying, "You're going to have an awesome day!"
