Arvinder ji pehla ta welcome here on UNP and now the gift for your wife.........umm............Make her feel extra-special on this birthday, rather than just bringing her a gift at home, Take her out somewhere, for a dinner maybe, Buy a beautiful card and write in what u feel for her, have words of appreciation how she makes your life a charm, and then give a her a small little gift, maybe a bracelet as Sonia said, or Order flowers as a surprise first thing in the morning...............hope it helps.........but try making the whole day special for her
