Some days... wonder if you can do one more thing, wipe one more tear, pat one more back. Some days start after you've spent the night rocking a feverish baby and you know from the dawn that there will be no nap. And you ask yourself if anyone notices that you're giving so much and working so hard and loving so completely. And once in a lifetime, on a day like that, your baby looks at you and says "Mama" for the very first time. And you know, beyond a shadow of a doubt, that someone does.
