The only Kardashian kids left to reveal in the holiday series are Reign's 5-year-old sister, Penelope, and 7-year-old brother, Mason, as well as Rob Kardashian's 1-year-old daughter, Dream.
Some fans, however, are speculating that the series of family snapshots are building up to Kim and Kanye revealing the birth (and possibly first photos) of their third baby. Their forthcoming addition to the family -- who is being carried by a surrogate -- is rumored to be due this month.
Kim told ET last month that she was in charge of the family's Christmas card this year, and that she'll "never do it again."
"Just to wrangle ever single family member was so exhausting," she said. "I thought it would be really easy. It was really tough. But it'll be a good one this year, I think our best yet."
