The Average American Spends $169 On Mother’s Day, $120 For Father’s Day

That is not so surprising if you count in the fact that Mom's stuff is costlier than Dad's. But as a stat it is still a good one to spot - the average spend on Moms is some 41 percent more than the average spend on Dads on their respective days (Source)

Not so surprising since Dads anyways spend less time with children in general.
