Sleep changes rapidly during the first year of life. Brain maturation is accompanied by sleep consolidation in several episode during day and night (daytime naps and night sleep) and progressive organization during the 24h period (more wake during day et more sleep during night). In the first months of life, sleep episodes are frequently interrupted by wake, possibly induced by multiple external and internal stimuli. One of this stimulus could be bladder voiding that is particularly frequent in babies. Only one team worked on the link between sleep and bladder voiding and reported that bladder voiding was associated with cortical arousal during a daytime nap in a little group of babies. In this study, investigators propose to study the relationship between sleep and bladder voiding in a bigger group of infant and during daytime but also nighttime sleep.
