I can only tell you what my mom did 33 years ago when I was born. She had my dad go back to the house after I was born with a blanket that I had been wrapped in. By the blanket having my scent on it my dad let Major (the dog) and Tippy (the cat) smell the blanket to get familiar with my scent. My dad did this for the 3 days that my mom was in the hospital....the animals were very relaxed when I came home and I think it helped the animals feel more at ease with a new human.

I would probally also take some one on one time time with each animal and the baby. Quietly taking to the baby and the animals, this way the animals still feel special and it gets them accustomed to the baby with you there to supervise.

While I have not tried any of this..I don't have any skin kids, but this is probally what I would do.
