Some may say the third time's a charm, but for the mom of six and one on the way, she'd probably say that the seventh time is a charm.
The Lair family already has six boys, which made the surprise of a little girl even more special.
The video showed the mom collapsing with joy after cutting into the cake to reveal the new baby's gender.
The family's reaction was posted to YouTube Sunday and already has more than 115,000 views.
Watch the video above to see the hilarious reaction.
