Which hospital are you delivering at? You can refer to the hospital list given by the hospital! :)
I started washing 1.5 months before my edd because I have too many baby clothes, swaddles cloth, bedsheet etc to wash. Need to split so many days because still got other household members clothes to wash as well 😅 If you’re using dryer then not much problem since it can dry faster.
It’s always good to prepare early as there’s many other things to do too. You can slowly start preparing and packing now! :)
Good luck!
