Your dog has been the center of your world so you need to teach him that being away from you is a good thing before the baby gets here. It's tough after a long day but you need to start giving him some time each evening that you are not paying any attention to him. By doing this and pairing it with something amazing, it will help him better adjust when you are ignoring them while taking care of the baby.
Put him in another room or kitchen with a gate up so he can't get to you. You might consider putting him in his crate when you are home from time to time too. Just make sure he can see and/or hear you. Give him a Kong filled with his food and corked with peanut butter or cheese. Stand near him and if he is focused on the Kong say “YES”. Slowly go into the other room without saying anything to him, you want him completely focused on the Kong and not you. Sit down for a minute and then go back. Pick up the Kong and let him out but don't give him a ton of attention. Kongs available at: Wigglyville Kongs
Once you start to see him get excited to go to that other room, make sure you only give him a Kong when he is being good (no jumping or whining). Slowly start adding some time each day you leave him in there, 5 minutes one day, 6 minutes the next, 8 minutes the next. Don't push to the point he starts acting out. If that happens, back up the time a bit.
This will help him associate you ignoring him with good stuff and will help when things get chaotic to have a space the has learned to go to quietly.
