I have a toddler and an infant. Or, to be more accurate, they have me. By the hand. Or the arm. Or the leg. Or the shoulder. Or all of these at once. Like most young parents of very young children, my wife and I are only barely keeping up with these two creatures that have a combined age that is still younger than most of the T-shirts in my dresser. Infants and toddlers are incessantly in motion. - See more at: http://www.edcentral.org/new-research-infants-toddlers-exhausting/#sthash.2EMaHDLm.dpuf
