Thoughts?

My sister lives with us and she’s a nurse , she planning on having friends over (nurse friends) sometime at the end of the month. mostly in the back yard but they will be coming in and out of the house to use the restroom. I told her I don’t think that’s a good idea if my baby is here by then I don’t want a lot of people over even though they are not holding the baby they are still going to be coming in and out of the household where my newborn baby will be. Do you think this is safe with everything going on?
