Guest blogger mom-on-the-edge: It's one of the worst sounds I've ever heard in my life. That bark. No, not the neighbor's dog. Whooping cough. The crying, screaming and barking started at one a.m. 

My son was sick. The wheezing was loud and his breathing was labored. I was the only one home to help him. No time to panic. Start the shower, sit in the steam. Check for fever. Was he hot or was it just from sitting in the bathroom for so long? Take his temperature. But, how? I've never done it before.

I find the regular thermometer and the one for his ear. I opt for the ear first. Press the button. Beep. Beep. Beep. I press it again. Nothing. When do I put it in? When does it start registering? This thing is on but I can't get it to take a reading! The bark. The wheezing. I have no one to turn to.

Should I take the baby to the hospital? I get the other thermometer. Can't put it in his mouth. Can't get myself to stick it up his tush. He's already so upset. I have no choice. But, first, let me see if I can get this one to work. Press the button. Beep. Why doesn't this damn thing clear? F it. I give him a small does of Tylenol. Prop some pillows up on the couch and he falls asleep in my arms.

For the first time, in my sleep deprived reign as a mother, I pray that morning comes fast. Bronchitis. The baby has bronchitis. The doctor said I did just fine and for future reference he showed me how to take his temperature. We survived.
