Brief summary

This is a study looking at the Happiest Baby on the Block technique. The investigators hypothesized that infants of mothers given a 30 minute videotape demonstrating the Happiest Baby on the Block technique would fuss/cry less and sleep longer than infants of mothers given a 30 minute videotape on general newborn care. The investigators also hypothesized that mothers given the Happiest Baby on the Block videotape would have lower levels of stress.

Detailed description

Mothers recorded their babies fussing, crying and sleeping on paper diaries when their infants were 1, 4, 6, 8 and 12 weeks old.

Results are based on ITT; 16 subjects did not complete any diaries and are not included in the analysis
