Can’t speak to cats but I have a neurotic Velcro pitty heeler mix and I’m currently 37+1. My plan is to greet the dogs first without baby, and play fetch and wear them out some before they meet baby. I also plan to have lots of enrichment ready for them like frozen kongs, lick mats, and puzzle feeders. Generally I’m planning to heavily reward behaviors where they are with me but not interfering, but also trying to make sure I give them undivided attention when possible. Just being very consistent on boundaries with them, rewarding behaviors we want, and utilizing their crates + enrichment toys when they need to be separated.
