Hi ladies! I'm expecting my first baby in October and we are planning to cloth diaper. I'm wondering about detergent. Watching YouTube videos has given me some idea, but many of them order the detergent online. Is there an acceptable soap I can find at my local grocery store?

Also, I've heard that I should prewash all of baby's clothes with "Dreft"... I'm curious if that would be a good choice for the diapers as well? Or if I could use whatever I buy for diapers on the clothes. It seems silly to have 3 different detergents in my closet of a laundry room :)

Thanks so much for your advice!
