Throwing your own baby Shower?

Ruby

So I have a question. My fiancé and I are expecting our first baby together. A little boy, we have thrown out the idea that we want a baby shower. I’m just shy of 32 weeks and my family has offered to help with the shower. His family has not. They don’t even talk about it until recently his mom asked when my shower was going to be? She said bc she has a lot of people that she wants to invite. Am I wrong for expecting that they help or throw us a shower? Isn’t it customary for a shower to be thrown for the mom to be vs throwing your own? Thoughts on this?
