This dataset contains estimated LIDS parameters from actigraphy recordings of 152 infants acquired at 3, 6 and 12 months of age. This dataset is the input data to the statistical models used in the manuscript entitled "Charting infant sleep cycle development using actigraphy: Longitudinal evidence for cycle lengthening within the first year of life from 35,000 hours of sleep". In addition, estimated LIDS parameters from the parents as well as a Jupyter Notebook containing the code to reproduce the statistical analysis are provided.
