Scary Story, Happy Ending

"Hey Renee! C'mere. You have to see this."
I stop in mid-stride and turn towards the bathroom. Joel had just finished giving Madelynn a bath and the other two kids were in bed already.
Madelynn is laying on her back on Joel's legs and she's crying. Joel points to her mouth and I look inside.
"Do you see that? What is that?"
I look closer at Madelynn's palate, the roof of her mouth. It's discolored, the color of green/gray playdough. I put my finger in her mouth to scrape it off and Madelynn just cries harder.
I feel a heaviness come over me and I groan inwardly.
Both Joel and I just look at each other.
"I'll go google it..." I lamely suggest and walk away.
I stare at the computer screen. The results of my googling didn't give much comfort: Cancer. Ulcers. Tumors. There should be no discoloration of a normal baby's palate.
I picture myself standing up in church asking for prayer for God to heal Madelynn. 'First Emily, then Rachel, now Madelynn?' This was too much.
I sit on the couch with the phone and thank God for a free 24 hour Nurse Help Line.
After a quick explanation to the nurse, we both agree that perhaps the discoloration is from the green veggies she ate today or the newspaper she was chewing on about an hour earlier.
I hang up, relieved.
A few minutes pass and an idea occurs to me. I find the newspaper Madelynn had been "playing" with and inspect it.
"Aha!" There was a small chunk missing! Joel and I agree to do a little "investigating".
"Q-tips," Joel suggests. I go grab them and bring them to Joel.
I leave the room as Joel forces Madelynn's mouth open but she just giggles. Finally she opens her mouth and Joel scrapes the palate with the Q-tip.
Then I hear laughter.
"What? Did you get something?" I ask.
Joel shows me something on his finger.
"It's a potato skin!"
