WIFE SWAP is the show in which each mom switches families for 2 weeks. The first week she must abide by that family's rules, and then they next week she switches to her own rules.
TRADING SPOUSES takes place during ONE WEEK ONLY with the theme being, "Is the grass greener on the other side." Each mom then decides how she thinks how the other family should spend $50 grand they are given.
Trading spouses is the definition of horrible reality television.
