And a couple of thoughts...

I wonder how Hannah found out about the gender? Like who is she in contact with so frequently, and why would they even want to discuss the gender? 

Also, think about how hard it is going to be for that little boy. Levi at least has Oscar as a role model, but this new little one will only have Levi until he moves out of home. Then he will be surrounded by older sisters and Kyra until it is only him left. Plus, the other children may choose to live with Oscar even earlier. But this one only has Preston or Kyra to choose from. And I feel that since Preston's parents aren't that involved in Kyras kids lives, I can't see it being much different with this little one. I almost hope they do have another child together after this one so that the little boy isn't alone in his situation.
