I originally intended to do at 38 weeks since 40 weeks is term, but my baby was big so we needed to have her early on the 38 week itself rather than 40th week, resulting in me panicking and washing and packing everything only 2-3 days before my delivery. Was I able to do it in time? Yeap. Would I do it earlier next time? Definitely yes. Do it once you hit 32 weeks and start packing your hospital bag. Don't wait and procrastinate like me. Lol!
Also, I washed everything that will come into contact with my baby with baby detergent and softener because babies are very sensitive, especially when newborn.
