Why did I create a Baby Registry ?

So I just recently had my baby shower . Well, only 2 people actually got me something from my registry. Don’t get me wrong , I appreciate every gift I received , but now I have way too much stuff of the same . For example , I got about 14 bath towels , so much clothes I could dress 3 babies , 3 security blankets , etc... and all the items I really need ,I unfortunately did not receive . So I guess I will have to purchase everything myself after all . I feel like I sound ungrateful, which I’m definitely not . I’m still gonna put everything to good use , but I guess I’m just frustrated, that I spend hours and hours creating my registry , picking each item carefully and it was all for nothing pretty much . I also can’t return anything , since I don’t have any receipts...
