There is a huge graveyard directly behind my babysitter's house. Recently, it has "expanded" n moved so near to the back of her house that she sealed the back of her house with a wall to the ceiling (the tomb stones are only 2 feet away from her house!), leaving only some tiny ventilation holes close to the ceiling. I wonder if there is going to be some adverse effects on my newborn son that is currently under her care during daytime. Shall I change babysitter immediately? Thank you.
