I was reminded this past week about how much attention an infant or toddler demands. My California grandchildren were staying with me for a week. My 11 month-old granddaughter is a study in perpetual motion. She doesn't stop unless she is asleep. She has been walking for a month so she is unstoppable. Even holding her takes a lot of energy as she is constantly moving. Having just spent three months working on infant and toddler developmental guidelines, it was a reality check to actually participate in those developmental milestones that I wrote on paper. I constantly gain additional respect for parents and caregivers who spend every day caring for the young. Wow! is it a full-time job!
