Hopefully it's not dangerous, but we've found the solution to Mila's nightly cough attacks. LET HER SLEEP IN THE VIBRATING CHAIR. It's slightly elevated so she's not lying completely on her back, allowing for the mucous to drain. It's really very fantastic. We've done it for three nights now. The first two nights, we put her to bed in her crib. An hour and a half later she was hacking up a lung so we moved her to the chair. The third night we just put her straight in that chair. Last night was the first night I have slept all the way through the night.
Like I said - FANTASTIC.
