We’re going backwards

So we are still in the process of moving but our second night in our new apartment the people upstairs left a tub or something running and it started flooding our apartment, somehow went through the fire alarm and set it off. So we had to move bubs crib back in our room but he doesn’t want to sleep in it he’s scared that it’s going to happen again. I know with time it’ll go back but all that hard work just to get him to sleep by himself and now we’re back at square one.
