Dogs are creatures of habit, and it will be helpful to keep their routine as consistent as possible. If you plan to change their routine, start adjusting your dog to any new feeding and walking regimen early so they can be better prepared for the baby's schedule. Doing so will reduce the number of changes taking place at once and may help lessen any stress for your dog.
It is also important to help your dog become accustomed to the new smells and objects that will be part of daily life with your baby. Allow your dog to explore and acclimate to any items that make noise, vibrate, rock or bounce, as well as your baby's sleeping and diaper changing areas and related items such as baby powder, lotions and diapers.
A great way to help introduce these new sights, smells, noises and movement is to start incorporating parts of your new routine before the arrival of your baby. For example, turn on any baby jumper, bouncer or toys that make noise or move for a few minutes a day, rewarding your dog for good behavior. For smells, you can apply baby lotion or powder to your hands on occasion and allow your dog to sniff. Dogs rely on their sense of smell, and familiarity with these new baby scents will help your dog recognize the baby as a part of the family. If possible, allow your dog to smell some clothing that your baby has used in the hospital or even the car ride home before you introduce your dog and baby.
