When the baby comes home, have the mother enter first with the baby. Then introduce the dog to the baby's items and then the baby. Do not let the baby interfere with the dog's regular times with you (i.e. feeding, walks, play time). Never leave your dog alone with the baby and do not let the dog sleep in the baby's room.
Remember children can hurt dogs. Don't get a dog for the baby--the baby is too young to learn about it. It is not a good idea for tem to "grow up together" because you'll be too busy to attend to the needs of both. Teach your child that a dog needs quiet when sleeping and eating. The child should pet the dog gently and use a calm voice.
