Investigators seek to determine if an online based intervention can be developed to target increases in childhood sleep. The primary objectives of this study are to determine if different messaging strategies lead to the longer sleep duration.Children aged 9-12 who sleep about 6-8.5 hours per night will wear a Fitbit for 11 weeks in order to measure sleep patterns. Participants will have a sleep goal to meet each night. Participants will be randomized to one of thirty-two study conditions and receive text and/or email messaging. Some study arms receive additional messaging with different content and frequency of delivery. The study involves one visit to the Children's Hospital of Philadelphia (CHOP).
