To give reassurance to parents, Philips would like to add algorithms to the NightOwl baby monitor to be able to measure baby behavior and physiology.

In this study, the investigators aim to investigate the applicability of in-house breathing algorithms, and to develop algorithms, for babies sleeping in a home setting.

The data collection will be divided in several sub-studies, either e.g. matching different development steps in the development of the algorithm or focusing on a specific baby population (e.g. specific age range). In general, babies will be monitored (audio, video, activity) for 24 -48 hours under their habitual sleeping conditions.

Step 1: 3 full data sets will be recorded of babies in bed aged 3 weeks to about 3-4 months, who are not able to turn over yet. Data will be analyzed and study set-up will be checked. Parents will be asked to keep a baby sleep diary and a questionnaire will be filled in at the start, with questions regarding the sleep behavior of their child. At the end, parents will be asked to fill in a questionnaire with sleep-related and feedback questions.

In step 2, 5 full data sets will be collected following the same procedure as step 1.

In step 3 12 full data sets will be collected following the same procedure as step 1.

After each step, the study setup including the algorithms, will be reviewed based on the obtained data. All modifications to this protocol will be submitted as amendments.

After step 1 and 2, the Mother and Child Care Business unit of Philips and other relevant stakeholders will be updated on the progress and findings by means of a (short) meeting and PowerPoint slides.

After step 3, a report will be written. The PowerPoint slides shared after Step 1 and 2 will be incorporated in this report.

Procedures Phone call

During the Phone call the investigators will:

• explain the study setup

• explain the exclusion and inclusion criteria. The criteria will not be verified until visit 1.

• if the parents or caregivers agree, an appointment will be made for visit 1

  1. Home visit 1 - about 45 min

     During the first home visit the investigators will:

  1. a. make introductions;
  1. b. explain the study again, if necessary, and answer questions;

  1c. together with the subject's parents or caregivers sign the informed consent form belonging to this study;

• confirm the inclusion and exclusion criteria

• Complete the BISK questionnaire (investigator will ask questions to parent and report answers in CRF) 1d. Provide parents a baby sleep diary and instruct them to complete it; 1e. place the study setup in the room the baby mainly sleeps in; 1f. plan the second home visit. 2. During the study (2 consecutive days, including the nights) The setup will monitor the baby's bed, and the baby when the baby is in bed. After the setup is turned on, during Home Visit 1, it will record continuously for about two days (during day and night), until the investigator comes back to pick the setup up (see also Home Visit 2, below). The recording happens automatically; subject's parents or caregivers do not need to do anything with the setup.

The investigators will ask the parents or caregivers to keep a diary of the baby's (sleeping) behavior and to note information of behavior influencing the baby's sleep (e.g. baby being ill, not feeding well) during the recording period or if there was anything out of the ordinary with the setup (siblings fidgeting with it, power outings etc.).

In case of emergency, the recording can be stopped by pulling the electrical cord from the socket.

3. Home visit 2 - ~30 min

During the second home visit, the investigators will:

3a. ask how the study went, and if the parents or caregivers have any feedback for the investigators (close out questionnaire, investigator will ask questions to parent and report answers in CRF); 3b. review the sleep diary for omissions 3c. Check the end time and study setup 3d. pick up the test setup.

After completion of the participation, the investigator will notify the recruitment agency to arrange the compensation.

• are unwilling or unable to provide informed consent on behalf of themselves, their baby and siblings;
• are unwilling or unable to comply with the study requirements;
