My sohnemann needs at night his pacifier eigtl. mur to fall asleep and, indeed, when it is time awake at night to fall asleep again ... between tumbles around the likes somewhere in bed. I'm not a fan of ultra-bright night light irradiation and my son that does not need, I was super happy to have discovered this pacifier. it finds that is again easily alone and can blissfully asleep immediately. as can mom and baby comfortable by sleeping) and they really shine even in the morning even if I wake him! during the day I put them only on the window sill and in the evening before going to bed, I think a few seconds before the lamp, that's enough. so there's nothing to complain about and therefore 5 star for quiet nights;)
