Rain and thunder sounds for babies bring a steady storm into the nursery, with constant rainfall and rolling thunder in the background. Thunder is included, so it suits people who like storms but may startle light sleepers or young children. The track runs for 4 hours, enough to cover a long evening sleep. If your baby is used to storm sounds, start it once they're down for the night and keep it at a soft level. Keep the volume low and the speaker well away from the cot.
