Baby shower after the baby is born?

Would it be tacky to have a baby shower for my daughter when she's around 7 months old? I know it's not traditional BUT when I was pregnant most of my family didn't know. Like, only my mom, my grandparents, my sister, the dad, and my uncle knew. I have a very large family and if I hadn't felt so much pressure from my mom while I was pregnant I would've had a baby shower. My daughter was also born 6 weeks early. I would like to have a get together where everyone meets her. She's 3.5 months old right now and with all the holidays coming up I don't wanna stress people out. So I was thinking sometime in the spring. Anyways, does that seem like a bad idea?
