Hi T.-
I have 5 cats and a 9 week old. All 5 have very different personalities and I expected them to react to my baby in 5 different ways. I was most concerned with one of my kitties and how she would react to my baby, so I made sure she was supervised closely.
What I did to prepare my kitties was anything that came into the home for the baby was inspected by all the cats, just by sniffing. Every so often they were allowed into the babys room to inspect, but they knew it was off limits as the door would always be closed.
We used a cat net on the buggy and a mosquito net on the babys bed to detract the cats from jumping in. They never did so we have since removed it.
I also walked around the house where the baby would probably cry with my laptop and an audio clip of a baby crying so they could get used to the noise.
Here's the site to find the clip....

Once baby was born, my hubby brought home her first hat, which was covered in the stuff from birth, for the kitties to sniff. They all had their turn sniffing, but it was no big deal to them.
All this may have been excessive, but to put my husbands mind at ease, I tried everything to prepare them. This of course went on over a series of months before she arrived, but her transition into the home was seamless.
Also, I have been in rescue for many years and have heard all the stories from people dumping their animals because of the baby or even just because they were pregnant. I wanted to make sure that my kitties were comfortable with the new arrival.
The one kitty that we were most concerned with now sits with us during feeding time and loves to sniff the babys feet. We are all happy as we can be.
One last thing, you know your kitties personalities. Work from there........
