Children younger than 2 are in a critical period of brain development that requires hands on learning. Screen time should be avoided beyond video chats with relatives. Children older than 2 are at a stage in brain development where tablets or computer apps can be implemented educationally in limited and interactive fashion, with parents still acting as the teacher. Parents still must play the key role in their child’s learning, using the device as a medium to interact and learn with their child. Educational apps offer much more to your 2+ year old child’s development than video clips or movies.
