Hello!
<span>Compared to other children, research finds children who have been in full-time child care programs are earliest talkers.
This comes from a research done by Ratib Lekhal and others, in a study for the Norwegian Institute of Public Health. In the research, it was found that children that go to formal child care programs between the ages of 1,5 years and 3 years had a better language development than those who didn't. However, who was the caregiver was an important factor in language development.
