Why yes, I did put my baby nephew to sleep in the bathtub, why do you ask? Oh, that's kind of odd? Well, desperate times call for desperate measures, my friend.
Tired baby who is recently mobile + no pack n' play or crib = baby gets to sleep in my tub where he cannot escape or harm himself (except for possibly his eardrums. Baby cries really echo in a bathroom).
As long as I don't throw the baby out with the bathwater I figure I'm fine. Where did that expression come from anyway? There is no expression saying anything about letting babies sleep in bathtub, so I think I'm doing all right.
You gotta do what you gotta do.
(By the way, I did not put him in there sideways like that. He wedged himself into that position all on his own. I supposed wedged is not the right word, although it does look like it. He can move, I promise.)
