The range of toddler development is from 1 to 3 years of age. Toddler safety is very important during this time since more accidents occur during toddler years than at any other stage of childhood. Consistent discipline is also important at this age, where temper tantrums may be daily occurrences. It is important for the child to learn from experience and be able to rely upon solid, consistent boundaries defining acceptable and unacceptable behaviors.
