alfjr24, hasn't either of your two children ever fallen asleep in the car? Have you ever had a child with reflux who'll wake up screaming when he's flat on his back, but will sleep 'like a baby' when he's in the carseat and the acid can't flow back up his esophagus?

The suggestion of the rolled-up receiving blanket is an excellent one; it's much more versatile than the "head huggers" you can buy at the store.

Good luck!
