I had similar concerns when my baby came along, especially with my doberman as she is so big.
I did get one of those cd's with babies crying on it but my lot paid it no attention so I don't think it was any help.
If you are getting the pram early on push it up and down the house and walk them with it empty, there is nothing more embarrassing than pushing a pram down the street with a large dog out in front facing you and backward bunny hopping all the way (this was cured with just a shorter lead, stopped her trying to get in front and then panicking).
I asked my husband to stay in the car with the baby until I had gone in and said hello to everyone, they hadn't seen me for 2 days so were very excited, I brought in some clothing the baby had worn so they could all have a sniff. When we did bring the baby in they were very interested and all were allowed a sniff, the novelty did wear off after about 15 minutes but with every noise he made they came rushing over to check him out.
The best thing I bought was a large metal baby pen with a babygate in it, I had the baby's bouncer in it so I could just pop him down if I had to leave the room or answer the door and not have to worry about him being licked or pawed. Now he has just started walking I've opened the pen into one long barrier with a gate, I have it splitting my lounge in two, dogs are still included in family life but are protected from a now grabby baby.
TBH the biggest poblem I have had is keeping the dog toys away from the baby and the baby toys away from the dogs!
Good luck with your plans
