You may wanna do it now. I ended up having to have my son at 34 wks due to preeclampsia and I didn't have no diaper bag prepared or anything set up for him everything still in the boxes lol. which he didn't come home until 11 days old so I had time in that time to pack his clothes and set up things lol

I ahould start now, I hate to say it but baby truely can come whenever he or she pleases

Anytime you like. You can do it now. Don't wait to late to start like me. I'm just finishing my baby's diaper bag today and I'm 37 weeks.
