I think anything after 30 is good. Earlier is fine if there’s a particular reason- military deployment, big move, Thanksgiving/Christmas holidays, etc. I’m going to do mine at 32-33 weeks, I did it about the same last time. It worked well.
I did mine at 32 and I thought it was perfect! I was big enough for cute pics but not too big to where i was uncomfortable and i had enough time to put everything away and up
I am due Oct 31st.. but i am high risk so i wanna be prepared but in September my daughter turns 5. And was thinking to do it in august but i feel its really soon i am currently 24 weeks.
