It is a big problem in baby girls that they always lose their ear rings/studs. Kids always touch on it and the screw becomes lose and finally it will be lost. So mothers hesitate to wear them golden ear studs. We can do one simple method to avoid it. After wearing them the ear studs, just apply some nail polish on the back side (where the screw and the stud joins). Nail polish acts as a good adhesive and it will remain for a long time and will not be damaged even after many baths. Now I have tried this idea on my kid's stud. But for more safety I check it every day. But still after a month, it is safe.
