Congratulation
s! First, the WTH feelings should start to subside once the out of control hormones slow down a bit, usually around the end of the first trimester. Then you can tackle some of the issues you are concerned about from a starting point of relative sanity. Second, if you got a Pyr through CGC training, you are going to find parenting a human a piece of cake

Parenting any baby, either human or canine requires a capacity to love unconditionall
y, look beyond your own needs, and be consistently patient and steadfast.
I have a 29 year old daughter, a 22 year old son and an almost 11 year old son. While my two older children were growing up, I ran a day care center and had numerous German Shepherds, Malamutes, and multiple rescues. While some of my day care charges were dog familiar, others had no exposure at all. And some of the rescue dogs were not socialized around kids. Most (and I stress most) dogs that already know their boundaries with you are going to accept your new baby as part of your family before they even arrive. My Shepherd knew I was in labor with our youngest even before I had a single contraction. She whined and wouldn't leave my side for several hours before labor pains started! When Patrick came home, we too put him on the floor and let the dogs sniff and investigate thoroughly with both of us right there as well. We have never had a problem at all, and Patrick has become a terrific ambassador with his friends about how to approach an unfamiliar large dog and how to properly pet and greet dogs you do not know. Just remember that there is never a single moment to leave dogs and babies together unattended, and that one rule should be absolute. And remember, there are lots of people here to help with the tough times as well as the silly ones, the exhausted ones, the stressed ones, etc etc etc..
