0237 Internight Variability in the Sleep Consolidation Process
Bibliographic record
Abstract
New parents are often concerned about when their infant will consolidate their sleep, a process referred to as « sleeping through the night ». While the proportion of infants who sleep through the night increases with age, studies have shown considerable variability among infants in this process. The majority of studies rely on questionnaires, where mothers are asked to report their infant’s sleep patterns over a specific period of time. However, infant sleep may also vary from night to night. In order to document night-to-night variability in infant sleep consolidation, this study aims to assess the percentage of nights that infants sleep through the night, during a two-week period at 6 months of age, by maternal report. Data from 37 mothers of typically developing infants (40% first-borns) were analyzed. At 6 months post-partum, mothers were asked to complete an infant sleep diary for 13 consecutive days. Based on these diaries, the longest consecutive sleep period (without interruption) was retrieved. Sleeping through the night was defined as 6 or 8 hours of consecutive sleep. The percentage of nights every infant was meeting this criterion over 13 nights was calculated. The mean longest consecutive sleep period (assessed for 13 nights) reported by mothers was 347.2±128.7 minutes (range:156.9-612.9). As hypothesized, a large inter-night variability was observed. Using a definition of 6 hours, mothers reported in average that their infant slept through the night 41.5% (±33.0) of the time (5-6 nights out of 13); using a definition of 8 hours, mothers reported that their infant slept through the night 22.1% (±29.3) of the time (3 nights out of 13). These preliminary findings show an important inter-night variability in infant sleep consolidation process. Questionnaires that assess whether infants sleep through the night over a shorter period of time may not capture this great variability. Mothers should be informed about this variability and know that even if their infant sleeps for 6 hours consecutively one night, it does not necessarily mean that this behaviour will occur every night.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
