You don't have to spend more money to use baby friendly detergent and dryer sheets etc. I just c use all free and clear it's not extensive and I love it works great they have fryer sheets as well and probably fabric softener but anything fragrance and dye free etc will work :-)
I used downy regular with my first baby and dreft soap.. that was 10 yrs ago.. Now on the market I see they made a new downy free & gentle liquid softener for babies so I will use that..
I use my regular laundry soap and softener. I even use the same drier sheets. If baby breaks out then I would change but till then it will save money and time.
