The pacifier Avent are not recommended you !! look really nice, but the rings light up only very weakly and after half an hour you do not shine! You have to have super long under a lamp hold then shine and hold. have also spoken with the Hotline of Avent where the problem really care war.Sie meant that you could not exchange yes the pacifier, since the others were equally and you were even designed by the luminosity of 1-2Std! That's for my 1-year not suitable as you comes to 20pm to bed and if after such a short time the luminosity ceases then you can him at night not wiederfinden.Wirklich not thought !!
