@cocoo_app: Most parents think putting baby to bed earlier means they'll wake up earlier. The data says the opposite. We tracked 176 babies and found that earlier bedtime leads to longer, deeper sleep — because it reduces cortisol buildup. Tonight: try 30 minutes earlier. Cocoo tracks your baby's sleep and calculates the right bedtime automatically. #babysleep #bedtime #earlybedtime #babysleeptips #wakewindows
