Not in the Know

So I've been getting baby advice left and right this week and I just have one question.  Well. I have more than one question, but here is the most pressing one:


I've heard from several sources that they would shower with their babies in the bathroom.  But why?


I can't figure it out.  I think it's because I'm not a mom yet and I don't have a newborn, but hear me out.


Scenario:


You feed baby or baby is napping or there is a window (albeit short) for a shower.
Turn on shower, warms up, hop in, and shower.  It takes 10 minutes, maybe 15 minutes.


In those 15 minutes, if the baby wakes up and starts crying, is it necessary to immediately jump out of the shower with shampoo in your hair to attend to baby?  Is there harm for the baby to cry it out for a few minutes?   Is there a study that shows that sudden baby injuries or god forbid. baby mortality higher when moms are in the shower?


Someone please explain to me why it seems common sense has been tossed out the window or is my brain no longer logical?


Thanks!
