Well Congrats to you!! We just brought home baby number 2 yesterday and so far they have been great toghether
Our olders Max and the new baby Milo are playing like old friends and when Milo conks out from exhaustion Max has snuggled him....Max has been a very good big brother and shares his toys and all......good luck, I just held the new baby and introduced them....and slowly let them get to know each other....took about a half hour but went well.....one suggestion, do you have a blankie that your first dog sleeps on? If so take that and wrap the new baby in it.....lets her get used to the smell....good luck
