after you have eaten certain foods for so many years your appreciation for its amazing taste & specialty doesn’t feel so special & unique anymore (as does anything, the more often you have it the less special it is & soon it becomes daily & loses its specialness) many people set aside special snacks for their children only for shabbos & other special times so that for chicnuch your children should look forward to the shabbos & the treats it comes with & it always remains special due to only getting it once a week
the way you feel is what we call THE HUMAN NATURE OF TAKING THINGS FOR GRANTED & this a human being can’t be blamed for, it automatically happens naturally due to having it often. but you can make it special again by stopping to eat it or use it everyday & only use it certain times & less often
