Infancy and toddlerhood is a busy time for children, who develop around 80% of their brains by age 3. Most of the development during this period happens during interactions and play with caregivers, so consistently showing up for your child and responding to their needs as best you can will support their successful development.

Items under warning signs, such as withdrawing from certain people or showing little interest in playing, might be a sign that something more serious is going on in a child’s life.
