When should I start planning the baby shower?

Becky
I am currently 12w 5d and we are planning on having it when I'm 28w that way I still have plenty of time to get what I still need after the shower and I will still have my energy to enjoy the shower. I've never planned a shower and don't really know how long it takes. When would you ladies suggest to start? We don't know the gender yet but hopefully soon ♡
