WASHINGTON (AP) _ Legislation in Congress is being filed to increase child-care workers' wages and comes after two studies last week cited America's day-care problems.

A bill by Rep. George Miller, D-Calif., would provide $5 billion over five years to states to increase child care providers' wages though stipends and offer scholarships. The money would come from existing federal funds.

``On average, child-care workers earn less than janitors, bus drivers or barbers,'' Miller said. ``It is young children in child care who pay the price for the poor quality of care that such low pay yields.''

One study last week described an ``alarmingly unstable'' work force at child care centers and says teachers leaving for better-paid jobs often are replaced by less qualified workers. Another found that children who spend many hours in day care are more likely to be aggressive and defiant.
