Introducing Baby to Isabel

We need to learn how best to help our first “baby” adjust to the new one that we will be bringing home very soon. Isabel came into our lives at 4 weeks old, a rescue from an ailing mother’s litter of six, and she has run the household since. We were told during her first year of struggle with separation anxiety that she was an alpha female, and required A LOT of attention. I had no idea the responsibility that laid ahead, the number of remote controls and furniture we would have to replace and the expenses that came along with having a pet. Despite all these obstacles, she’s become a part of this family, and it will be important in the coming months to help her cope with the big change that’s to come. We’re not really sure what the best approach is, and would love advice and tips if any of you have experienced this in the past. Should we begin introducing baby fragrances to the home? Should we start taking her for walks alongside a baby carriage? Should we gradually accustom her to spending less time with us?
My godson was born 8 months ago, and we slowly began introducing him to Isabel. They get along beautifully, except for Isabel’s desire to constantly lick his face. He giggles and laughs, which only encourages her to continue – so I’m certain that it will take some effort to get her to stop. While she is much more gentle and sensitive with Nicola than she is with adults, she doesn’t like when he’s the center of attention. She subtly gets in the middle if I’m playing with him, and insists, in her own obvious ways, to focus on her instead.

We're looking to begin preparing Isabel before our baby arrives with a few first steps. Please leave a comment if you have any other tips:
• Enroll her in a training class, and practice training techniques
• Introduce her to baby-related noises
• Introduce a baby doll to help her get used to the real thing
• Sprinkle familiar baby smells around the house, like baby powder or baby oil
