There is a significance of gifting young girls between the age group of two and five something during Navratri. Young girls are also worshipped during this time. It is said in Hindu Puranas that gifting nice things to young girls during Navratri pleases Goddess Durga and blesses the devotees fulfilling their wishes.
According to Hindu traditions, there is an importance of gifting certain things to girls each day for 9 days. On the last day, girls should be given red chunar/chunni, books of Durga Chalisa or a red-colour dress as gifts.
For instance, on the first day, young girls should be given flowers as it is considered auspicious. If you want to please Goddess Saraswati, present a white flower garland to girls. For a happy life, gift red flowers to girls.
