I saw a sign in my doctor’s office that said that babies who interact with dogs and cats develop stronger immune systems than babies who don’t. So the cat licking the baby’s face, or the dog sniffing the baby’s ear–those are not bad things.
When I was still only three years old or so, I tried to change my baby brother’s diaper. I’d seen my mother do it; how hard could it be? All you’ve got to do is dump half a bottle of baby oil on him and then liberally coat him with baby powder. That’s when my mother came in and put a stop to it.
No cat or dog would ever do that to a human baby.
