Sister stars in adorable time-lapse pregnancy video

Sharing the magic of a pregnancy with a toddler is one of those experiences that's just too wonderful not to be documented.

2-year-old Amelie is one of the stars of a video about her little sister getting welcomed into the world, and her enthusiasm makes the video that much cuter.

Mark and Anna Sansone of Japan made this time-lapse video using a combination of photos and videos to make the time-lapse match the look of stop motion.

This isn't the Sansones' first pregnancy project. When they were expecting Amelie they made a similar video that has since gone viral--it has more than 11 million views.

"She certainly doesn't know her video became popular," Mark said of his oldest daughter.

But Amelie enthusiastically went along when it was time to make little Mila's video, and it turned out to be a good way for her to learn about what was happening, too.

"Amelie is just starting to understand that people grow up," Mark said. "And this video was a great device to use to help her understand that she was going to have a baby sister soon."

Mark said Amelie is beginning to understand what growing up is like--and that it will happen to baby Mila, too. He said Amelie says things like, "Soon she'll be big enough to eat dinner with us!"

Just as the experience was surely a little mystifying for the 2-year-old, the video culminates to a magical climax. Instead of coming in through the door, though, Mila gets a more imaginative entrance.
