Primary Outcome Measures:
  • mean duration and change over time for total duration per 24 hours for crying variables [ Time Frame: 5 and 11 weeks corrected age ] [ Designated as safety issue: No ]

    mean duration per 24 hours for following variables: content, fussing, crying, unsoothable crying change over time, measured at 5 and 11 weeks corrected age

    measured by diary



Secondary Outcome Measures:
  • mean sleep duration per 24 hours and change over time [ Time Frame: 5,11 and 25 weeks corrected age ] [ Designated as safety issue: No ]
    mean sleep duration per 24 hours measured by sleep diary measured at 5, 11 and 25 weeks corrected age, for adressing change over time

  • mean weight gain per day [ Time Frame: during hospital stay ] [ Designated as safety issue: No ]
    mean weight gaing per day during hospital stay.

  • mean activity count per 24 hours and change over time [ Time Frame: 5, 11, and 25 weeks corrected age ] [ Designated as safety issue: No ]
    mean activity count per 24 hours measured by actigraph recordings measured at three time points, 5, 11 and 25 weeks corrected age to adress change over time
