Twin Pregnancy Time-Lapse Video Captures Family's Joy From Gender Reveal To Babies' Birth

A mother has captured her pregnancy milestones up until the birth of her twins in a beautiful time-lapse video.

Heather Tomoyasu, from Brooklyn, America, took photos with her husband and their two-year-old son to share their pregnancy announcement.

Tomoyasu and her son then posed for photos wearing the same clothes a few times every week and edited the snaps into a stop motion video.

The pictures capture their growing excitement as they discover the sex of the babies.

And document Tomoyasu's growing baby bump.

Right up until Tomoyasu gave birth on 6 October 2015.

One day Tomoyasu says she'll show her twins this video as proof of their prenatal fame.
