About 40% happy and 60% "oh shit, what did I just do?"
Haha. Been there!
Okay, so congratulations then! That % is going to change real quick. K was a BIG surprise for us too and I went from scared tears to OMGOMGOMG to OMG? Yay? to WHEEEEEEE within less than 24 hours.
Since this is mostly a timing issue, take some deep breaths, gear up for smelling everything under the sun for awhile, and give your H a big hug. You've totally got this.
