2nd baby shower

I have a son almost 2 years old (20 months old) and I’m 6 months pregnant with a baby girl. My mom and my aunt threw me a baby shower for my son. this time around I don’t expect anyone to throw me one because other than my mom I don’t know who would. my husband thinks we should just have one ourself. Is anyone else planning on having a second baby shower? Or throwing one yourself?
