We're Expecting Another Baby!

No, no, no!  Not My Bob and me, but our son and DIL, Austin and Melissa.  This will be their third and they tell me, final.  They would like a girl, since they have two boys, and they seem very happy about the prospect.  Bob and I are also excited, even though we always have our concerns.  Austin and Melissa  seem to already have too much going on in their lives and never seem to quite be settled.  Austin told me that he wants a third child and is happy about it, but he also wished that their lives weren't so chaotic.  I told him at this point he better just go with the flow because it's probably not going to get any less chaotic for the next 18 years or so.
They are back to thinking they should now move closer to Austin's recruiting office.  They had given up on that idea and he had decided to just stay in their house here in town close to us, but now he feels he should live closer to his office with Melissa being pregnant and the new baby due in July.
Melissa quit her job about a month ago in order to stay home with the boys.  So this news didn't come as a complete shock to me.  Especially after they laid eyes on their beautiful baby niece, Riley, after she was born in May.  I could see the look in their eyes then that they wanted one, too.  But Melissa just signed up for the Air Force Reserves.  Since she was already in the Air Force about five years ago, she's now in the reserves as a photographer, which is what she started out in.  She signed up for the reserves, though, before she was pregnant and this is her first weekend of training.  She will be gone one weekend a month.  So we'll see what happens.  I have nothing against her being in the reserves at all, but see what I mean about just adding to the chaos?
I'm getting better at telling myself it's their life and that's my constant mantra right now.  I just keep busy with my own life and hobbies and I'll help whenever I can.  I certainly can't take on their hectic lives. 
One thing I know for sure, My Bob and I can't wait to hold another new baby that just amazes us with the love we feel for them.
Speaking of beautiful grandchildren that we love, here is the most recent picture of Riley in her high chair for the first time.

Is she a princess or what?
