This is going to be a dangerous situation should the dogs ever fight around the baby so they need training help now to resolve this.
http://www.apdt.com/ to find a trainer to work with or asking their vet for a veterinary behaviorist referral to work on the problems before the baby arrives.
The book Childproofing Your Dog by Kilcommons and Wilson may also be a help.

If the baby is crawling and the dogs have a fight they may not even intend to hurt the baby but still could in the heat of battle or by stepping on the baby.
Hope this helps you!
