I have 25 brand new smart bottom 3.1's that were gifted to me. Everything online says to wash them about 8 times which I not a problem but I was wondering how to go about this. I'm assuming throwing in a load of just diapers isn't ideal so I was going to mix with my every day (not diapers) laundry. How many diapers should I put in a medium to large load? I use tide powder and hot water if that makes any difference? TIA!
