A new study reveals that children who spent more time in daycare were protected from their mothers' emotional exhaustion.

Dr. Julie Turner-Cobb of Bath University and Dr. David Jessop at Bristol University carried out the research. Dr. Turner-Cobb says that children were not affected by the mother's emotional feelings about work if they attended daycare.

"It can help protect children from the effects of their mother's low job quality, he said."

"Ensuring that mothers of young children have good support in the workplace is essential for supporting both mothers and their children." said Dr. Turner-Cobb.

The findings are based on tests recording levels of the stress hormone cortisol.
