baby backdraft

During a tantrum: the dreadful pause that follows a baby's initial scream, as it sucks back more air, to release, an even louder, longer, more ear piercing shriek.

I was just settling into my seat on the plane, when a disgruntled baby nearby let loose with a blood curdling wail. Then came the baby backdraft. It took in a huge gulp of air. I sat helplessly in that half second of calm, waiting for the deafening howl to fill the cabin.
