If you have four-legged members of your family, it’s a good idea to start getting your dog or cat used to the idea of an infant in the house.

Before your baby is born:

• A visit to the veterinarian will ensure that your dog or cat is in good health and up to date on all vaccinations.
• If you won't want your pet sleeping in your bed or jumping on the furniture anymore, establish these boundaries ASAP.
• Put your baby's things in place—the swing, portable crib, bassinet—a few weeks in advance. Let your pet become accustomed to the new items and the different sounds they make.
• Find a spot that will serve as the "pet area" and begin having the animal spend time there. 
• If you have a cat: You can download "Baby Sounds for Pets" and play a few minutes at a time. Beware of crib climbing. Move the litter box and cat food away from areas where the baby will be present.
• If you have a dog: Consider taking your pooch on walks with the stroller before your baby arrives. Avoid rough-housing or playing tug-of-war with your dog. Work on a no-begging policy.

After your baby is born:

• When you get home from the hospital, say hello to your dog or cat without your baby present at first.
• Have your dog or cat sniff your baby’s blanket from the hospital to help them get familiar with your baby’s scent.
• Sometimes it's a good idea to keep the pet and child separate for a few hours while the pet gets used
• For their first introduction, your dog should be on a leash in the sit/stay position and rewarded with petting or praise. Gradually, your dog and baby can be brought closer together.
• The same holds true for cats – hold your baby near your pet, and caress and talk soothingly to the animal.
• Don't exclude your pet from your new family. Stick with the animal's regular routine and try your best to spend a little one-on-one time with them each day.
