How clean is your clean house?

I'm 38 +4 days pregnant. Baby will be here anytime (let's hope) and I'm trying to get my house as clean as I can. I have 2 cats and a dog. The couch gets the most use by all of us and I keep blankets on it to try to help with the cleanliness but dogs are in and out all day of course. I'm just wondering how insane I have to make myself about pet dander here and there. We vacuum maybe every other day and run a mop at least once a week. How often are you cleaning the couch (if u have animals) ect... I don't want to get my baby sick but I also just don't believe people are steaming their furniture everyday... but maybe they do? lol thanks
