Our first children

So this is Dewey and Gertrude. I got Dewey before I even met Josh, when this sad little emaciated dog was wandering the parking lot at work. He soon became my confidante and eventually Josh's best buddy (at least that's how they appear whenever you see them together). Dewey is hands down the best dog anyone could ever ask for and I cannot imagine life without him.
He's been through puppy classes, learning that cats aren't chew toys and the eventual adoption of his little sister/girlfriend/wife/foe, Gertrude. To say that Gertrude has been a challenge is really being nice. She has her moments of total cuteness and she's finally coming around but, to put it nicely, she's stupid. Flat out stupid. She's almost as big as Dewey but has yet to grasp that she can jump on the bed herself (she's 7 months old!!!). Instead, we either have to watch her struggle to get on the bed or grab her by the ears and help. Also, we're still shaky on saying she's housebroken. But, we love her just the same. Well, after months and months of threatening to get rid of her. I guess I'm starting to wonder how these little guys are going to adjust to life with a new baby. Personally I'd like to believe they will be angels and everything will go smoothly. I have no doubt whatsoever that they will never attack or feel threatened by a new baby. Rather, I'm worried baby will get too much loving from them. Also, why is Dewey so standoffish from me lately??? He was really needy and protective of me, even before I found out I'm pregnant. Now he's finally starting to come around to me again, after almost a week of sleeping on the floor.

I need some suggestions on how to make this transition easy. There is absolutely no question that these dogs will forever be a part of baby's life, no matter what. We will all have to learn to adjust!!
