Title: Why only work on a timer?
Review: You can't leave this on for more than 23 or 45 minutes. If you could leave it on for more than 45 minutes I think it would help create a better environment for a baby to stay asleep or soothe him/herself back to sleep when s/he wakes after 30-45 minutes. Why not just have an "On" setting? Pretty silly design flaw
