Cold/flu has hit our house

My daughter is really sick with a sore throat, coughing, can barely breath she is so full of congestion. It’s making its way to me as I’ve had loose stools and a sore throat since last night, and now it’s just to see if the rest will get it. My main concern is this hit the house just after we set up everything for the baby 😭 I’m worried the germs will stay on the items we have set up?! What do I do?! I’ve been cleaning the past month with thieves but am doubting it Because we never get sick and then when I stop using Lysol it’s back to sickness. I don’t want to put Lysol on things the baby will be on either as it’s harsh I just don’t know what to do
