I've found that with certain types of dogs (my experience is with staffies) they're the baby of the house until there's a new baby at which point they become the protector and they get a bit more 'OK time for me to stop dicking about and help out around the place'.
I think if you prefer your dog to be more engaged you can fuss over him more, but I think he's just trying to recognise the potential shift in the pecking order - you can communicate to him that his position hasn't changed by continuing to play with him and making a fuss, or you can just accept your New Good Dog as a bonus of having an extra human!
Well good, and bad news. He is clearly over his depression at the new arrival and back to normal, if not acting up a bit. Hopfully in a few days he will settle!
