Paco is getting less attention, but could boxers generally show resentfulness towards a newborn family member?-D
I think this last sentence could be a major root of the issues you are experiencing with Paco. I know it is difficult with a newborn, but right now Paco needs extra attention and love from his family members, especially his human, whether that be you or your wife.
Boxers do not generally show resentfulness towards a new family member, but they can get extrememly jealous. I don't mean in an agressive way either. Usually they will start bad behaviors such as eliminating in the house or just your basic destruction, such as chewing on furniture, things of that nature. When you wrote that Paco tried to chew the baby's head, I would have to see how he tried to chew the baby's head. Was it licking the baby's head, or was it biting at the baby's head? Did the baby have a hat on then? I would give Paco a piece of the baby's clothing, a hat or t-shirt so that Paco can get used to the baby's scent. This actually should have been done before you brought the baby home from the hospital.
Do not EVER leave the baby unattented with Paco or the other dogs. You need to supervise all the interaction between the two. Don't ever scold Paco for the unwanted behavior around the baby. You need to teach Paco how to act around the new family member. You need to teach Paco how you want him to approach the baby. Praise, Praise, Praise Paco either with treats or a ton of extra attention whenever Paco acts appropriately around the baby.
I think the worst thing you could do is seperate Paco from the baby. They both need to get used to each other, they are both family members and seperating the two will only lead to other unwanted behaviors and jealousy. Paco needs to learn all the new smells and sounds that come with bringing a new family member home. He will soon understand that this little new bundle is not going anywhere and will accept him as part of the family. Here is a good article on introducing a new baby in to the home. Good luck with this, I'm sure Paco will be back to normal in no time!
