When it comes to dogs and cats, familiarity is all about scent. Because of this, introducing your newborn to your pet can start well before you bring the baby home. Before arriving home with your baby, have your spouse or partner bring home a blanket, undershirt, or bootie your baby has worn in the hospital, so that your dog can give it a good sniff. This will give your dog a head's up that there's soon to be another member of the pack.

When you finally bring your baby home, have your spouse or partner carry the infant inside and into another room so that you (the mother) are available to give the dog undivided attention when you walk in the door. Since you've likely been away for a few days, your dog will be seeking affection from you. After 5 to 10 minutes of interactive bonding time with your dog, you're ready to introduce him to your newborn. Offer a toe - never the head - for the dog to inspect and sniff. If your dog isn't interested, don't force him to inspect your baby. There will be plenty of chances to try again later.

A few notes regarding safety:

• Get routine exams for your pet and keep all vaccinations up to date.
• Give your pet regular nail trims so they can't scratch the baby.
• Never allow your pet to get in the crib or the bed with your baby, as they could cause injury or suffocation. 
• You can use double stick tape around the edges of baby furniture or the changing table to keep pets from jumping up.
• Use safety gates to keep animals away from the room where your baby sleeps.
• In the event your newborn gets scratched, wash the area with soap and warm water, and apply an antibiotic ointment. 
• Notify your pediatrician if you think additional treatment is needed.
