Baby shower irritated!

So I was telling my mother and sister I wanted a baby shower.. they literally like shot down the whole idea saying its that a baby shower shouldnt have this or that or etc. They said im throwing a baby shower to entertain everyone 😑 in really disappointed it's annoying. Like if your financially for paying for it then what's the point🙄 they went on to say you have more important things to buy like blah blah blah. What is the point of a baby shower
