I'm glad you are thinking about this now - preparation is the key to a smooth introduction, and will lay the foundation for a good relationship between your dog and your baby.
Since I do not have children I can't give you first-hand experience - so theory will have to do in this case.

Here are some good articles from the ASPCA:

Have you found a trainer to work with? My oldie's trainer, herself a relatively new mom, is thinking of setting up a 'dogs and babies' lecture - unfortunately she is in ZH. If you wish, I could ask her if she knows of anyone in the Geneva area who does something similar.
I would also recommend a dog forum, the Dogpages Rescue Forum. The topic comes up regularly, the voices of experience are always happy to chime in:

But I'm sure that there are many EF members here who can give you the benefit of their hands-on-the ground (or lead

) experience.
Congratulations on the upcoming arrival - and wishing the whole family, human and canine, many happy years together.
