Is having a 3rd baby shower tacky?

Hey guys, quick question. I am pregnant with my 3rd daughter and we are super excited to add her to our family! My question is with my first daughter my mom held a shower for me because I was having a baby, but also because I had just left a toxic relationship and was going to be doing everything on my own. A couple years later I got pregnant with my second daughter, but this time I am married and going to have more help. We weren't going to do a shower, but because my husbands family wasn't able to celebrate my first born we wanted to do a shower so his family could be involved. Both showers I was lucky enough to have amazing turn outs! Well the years after we tried to have more kids, but with no luck and we decided to start giving our stash of baby girl items to family members and friends in need. Well, a long 5 years later we found out I'm pregnant again and my sister wants to host a shower for us.... Is it tacky to have another shower where we will be starting over completely? Or is it acceptable where it has been so long? We have no problem buying everything we need ourselves we just aren't sure how people will perceive an invitation to yet another shower. Please no rude comments.
