The Wildrose party is promising families a tax credit that would give parents $200 per year for each child.

"For a family of four, the Wildrose Child Tax Credit means they can count on an additional four hundred dollars per year to help manage their household budget," said Leader Danielle Smith while visiting a daycare in Sherwood Park.

She estimated the promise will cost taxpayers $130 million, but the Conservatives are questioning Wildrose's math.

They say the real cost of the program would be closer to $180 million. 

The child tax credit is the first of three components to the Wildrose family platform.

The remaining two components will be released later.

The NDP also made promises to Alberta families Thursday, with Leader Brian Mason offering to cap costs for daycare, halt school closures in mature neighborhoods and freeze tuition for university students.
