Stephen Harper's Children Then And Now (PHOTOS, VIDEO)

When did Stephen Harper's children get so big?

On the front of the Harper family's otherwise unsurprising 2012 Christmas card, the prime minister's son Ben is visibly taller than his father. Ben's impressive 6'4" stature has helped make him one of the country's top volleyball prospects.

The prime minister's 13-year-old daughter Rachel also seems to have grown up quite a bit in the photo for the card.

The noticeable jump in maturity shouldn't come as much of a surprise. Harper reused a photo from 2010 for the 2011 card, making the childrens' growth seem all the more dramatic.

Even still, it seems a little strange to see the Harper kids all grown up.

For the nostalgic types, here's a look back at how things used to be.

Clarification: A previous version of this story included information from an off-the-record party held by Harper for the press. That information has been removed.
