Third baby shower?

Athena • Mom of two princesses ❤️ AEC AJC
I am currently pregnant with my third child. My daughters are 17 months and 6 1/2. I am due with this one at the end of February. I had baby showers for both of my daughters. My SIL wants to throw me another one but I'm not sure how to go about it being my littlest one is so...little...I feel like I just had a baby shower. Should I consider having a third baby shower? Any thoughts??
