This study examined the relationship between parental bedtime strategies, infant sleep fragmentation, and negative sleeping/waking behaviors. The researcher hypothesized that certain bedtime strategies would be associated with more fragmented sleep, and that insufficient sleep would correlate with negative behaviors. Parents completed questionnaires about 40 infants aged 1-48 months. Results supported both hypotheses, finding co-sleeping linked to more night wakings, and frequent/insufficient nighttime sleep associated with poorer waking behaviors. The discussion concluded certain strategies like co-sleeping disrupted sleep, and healthy sleep should be encouraged to parents.
