A True Lamdan

On ליל שבת the kids were playing with Kapla, and Yehuda Leib kept messing it up.  So one of them decided to move him out of the way....by putting him in one of the bedrooms and closing the door.  I was in the kitchen, when I heard YL's desperate cries...and discovered him in the dark room, banging on the door, with a petrified look on his face.  I promptly gave the kids a mussar shmooze about how you can't do that to a baby, especially in a dark room- it was so scary for him to be closed up in a room by himself, without being able to see anything.

Well the next morning, the kids were busy playing again, and YL once again started bothering them.  Before locking YL up again, our little culprit went through the following thought process:

(gemara niggun) Mommy said its not nice to lock a baby inside a dark room because he's scared of the dark (raising fist with thumb sticking upwards) But, if you turn on the light in the room, lich'ora that should be okay!

Needless to say, I had to expound on the previous night's mussar shmooze, explaining that it is never okay to lock a baby in a room, whether or not its dark, and its certaintly not okay to turn on a light on Shabbos!
