You probably don't need to be told this one. I bet you go into your kids' rooms at the end of the day and make sure that they are still breathing. You cover them up if they've kicked off the covers. You check to make sure the room isn't too hot or too cold. Maybe you refresh the water on the nightstand.
You should also just stand there for a minute and look at that little face in repose. See how sweet those little eyelashes are against her cheek? Look at that little bow of a mouth as he breathes in and out. Isn't it funny how they sleep with their behinds in the air or their arms flung out to the sides?
Now try to remember this moment tomorrow. When she decides that the bananas are too brown and throws them in the trash where you just put the raw eggs. Remember this when he colors on the carpet with the special permanent markers he found on Daddy's desk. Picture that sweet little body tangled in the covers when she has dressed herself in your silk blouse and then washed her baby doll in the sink.
Take a moment to drink in the beauty of a sleeping child. It might help your child make it alive and kicking to the next night.
