JC, first wash, I used washing detergent + vanish + hot water setting. 2nd wash, as still got 2 pcs with stains, I rewash again, repeating 1st wash. 3rd n 4th wash, I juz use hot water setting w/o detergent. 5th wash, plan to wash with baby detergent + softhener at date nearer to delivery.
First time mama.. Do as I felt should be alright. Pai seh if steps a bit too much. If got someone helping u, i think do hand wash or brushing after soak with hot water should be more effective.
