It's a boy💙 and I'm terrified! Need boy mom advice!

So I need advice on how to get excited about having a boy. I know nothing about them. I've only ever really been around little girls, and really thought I was having a girl. I'm terrified because I'm absolutely lost on how to raise one, etc. with a girl is be jumping in head first because I'm comfortable with them and my sister is 16 years younger than me, so I practically raised her. I just want to know your favorite thing about being a mom to a boy, and any boy tips, or products I wouldn't think of!
