Baby shower after first child?

C
I'm due with baby #2 in September. We had our son in 2015 so he will be 2 in July. We decided not to find out the gender of this baby since it will more than likely be our last. 
Did anyone have another baby shower AFTER their first child? I know a lot of people don't. I would LOVE to have something celebrating this child. We don't need any big items because we were smart and got gender neutral items when we had our son and not that we need help getting clothes, etc. But I think every child needs to be celebrated in some way but no one has mentioned doing anything and I'm already 20 weeks.
