To get started, select an age range from the pull-down menu and click on it. Depending on the age range, different hotspots on the brain will appear.

ZERO TO THREE's podcast series, Little Kids, Big Questions, addresses some of the most common (and challenging) issues facing parents of babies and toddlers, such as: helping a baby learn to sleep through the night; dealing with a picky eater; and learning to set limits on children's behavior.  Each of the 12 podcasts in this series features an interview with an expert that focuses on how to apply the research of early childhood development to daily interactions with babies and toddlers. Little Kids, Big Questions is hosted by Ann Pleshette Murphy, a past contributor to ABC's Good Morning America Parenting Segment and author of several parenting books.
