A toddler is a young child, usually defined as being between the ages of one and three. Registered nurse, midwife and author, Robin Barker, states 'Any time from eight months onwards your baby will begin to realise he is a separate person from you. He will find it exciting to be able to move away from you but scary when you move away from him.'
The toddler years are a time of great cognitive, emotional and social development.
