For those of you that don't know what a wet bag is it essentially is a fabric bag that is laminated on the inside with fabric on the outside and holds dirty cloth diapers. It is a must for any diaper bag.
I do get the question, " Do I really, really need a wet bag to cloth diaper?" The black and white answer would be no but I tell people that if you store a dirty diaper in your regular diaper bag with all of baby's items it could get fecal matter and urine all over everything. That just wouldn't be good. Especially if you spouse or partner went into the diaper bag to find the soiled diaper contents all over the adorable outfit he or she purchase while baby was in utero!
The wet bag at our house is multi-purpose for us. In the summer time we also use it for wet swim suits. We do have a couple large wet bags so we can put wet towels,etc inside. I am especially loving the Planet Wise Wet Bags. They are the only wet bag on the market that has a 100% waterproof wet bag and has designed a patent pending method of even sealing the seams.
I definitely say a wet bag is a necessity when cloth diapering.
