Baby shower Theme Ideas!

I know it’s too early to start thinking about this, but I’m the type to set money aside and just plan things out already, but the one thing I’m so stuck on is a theme! My boyfriend wants avengers (I know, cute) 😂❤️ and I’m not against it! But I was thinking maybe something a bit more cute and baby... haha if you ladies have any ideas, please send them over! I’m brain dead 😫 I’m not looking for a gender colored baby shower either. Thank you in advance!! ❤️
