Infant interest in the environment has become much larger.
The second: the baby in 8 weeks or so found that the surrounding environment is not uniform, but also by the activities of the composition of the specific things (such as our own hands). So many new impressions initially give rise to fear contact with the mother, the most help to eliminate this fear.
