Study Arms:
- lifestyle counseling (Type: NO_INTERVENTION): The positions in the car safety seat and in supine 15 degrees anti-Trendelenburg are compared on the basis of a 20 hour pH monitoring. In one group the infants were first continuously positioned at 45 degrees elevation in a car safety seat (car safety seat type Maxi cosi Citi for infants from 0-13kg). During the next period the infants were kept in a supine 15 degrees anti-Trendelenburg position (hospital infant bed), and vice versa for the other group.

Based on this trial design, predict the completion outcome and termination type (if applicable).
