We bought these pacifiers for our son because he always cries at night and his dummy is not accounted for. We are excited about the Aventschnuller, but this one did not deserve the name "Night". Although we have laid the charge throughout the day in the bright light, the pacifier, the pacifier have shone no 10min. Unfortunately, this is very weak. We will continue to buy Aventschnuller because our son only accepts these pacifiers, but with glow in the dark, that was then probably not. Too bad.
