My family on my first pregnancy 😓

M • ❣️
This is my first and I'm 20 years old, ever since I've been pregnant my older sister and my mum have both been like "ok we are going to do this" "you're going to buy this" "you need to do this" "at this time I want you to do this" and " I don't want the baby with your inlaws" 
Like BACK OFF! I'm so over them thinking I'm so incapable I'm open to help but only when I ask I don't need them telling me what I can and what I shouldn't buy. It drives me insane when I'm infront of them and there making all these big plans with MY baby. I appreciate that they want to help but I will ask when I need it. Any advice?
