I used Purex Baby. $3 a bottle and everything was done by 36 weeks

36 weeks all natural fragrance, chemical free detergent from Trader Joe’s

I washed some around 37 weeks, but not all of it, since I didn't know what would fit him. Good plan, too. He came out 9lbs so most of his newborn items were too small and got returned.

We just used All Free and Clear, since it was good for sensitive skin and didn't cost an arm and a leg like special baby detergent.

I was at 30 weeks. I use Dreft baby detergent.

I started washing everything around 38 weeks and I used tide lol baby detergent is too expensive for me 🙄
