Make every new experience for your pet as positive as possible. As you bring new baby gear into your home, pair it with treats so that the big scary stroller and swing will become not so scary for your pets and eventually a normal part of life. Use a baby doll to help your pets get used to the real baby. Carry around a swaddled doll, take it in the stroller when you walk your dog, and use it to get your pets used to routine baby activities, including bathing and diaper changing. Train your pets to remain calmly on the floor beside you when you are holding the doll until you invite them on your lap.
