A.V.
When my daughter had colic and the reflux as well and there were plenty of nights where she slept in a swing. I believe that its Graco that makes a vibrating bassinet (I bought mine at Once Upon a Child-second hand) and I rolled up a couple of towels to elevate her so she wasn't laying flat on her back. She also liked the Fisher Price aquarium bouncer that vibrated and she liked that because of the lights and music as well. Her reflux went away as she got older. Good Luck!
