Just so you know HOW much I enjoyed it, I don't actually care for MPreg that much - so many fics are horribly done when it comes to that, which is unfortunate.
When it's as well done as it is here (and like the Breathe Series), it is a joy to read. The use of the time changes were effective too. You did a great job balancing between all the timelines and that's not always easy to do.
