We use the Seventh Generation Diapers on our 15 month old daughter and have been using them exclusively for the last 6 months.  These seem to fit her better than any other diaper we have tried.  The tabs are wide and stretchy and the diapers are soft and absorbent.  We have not had any problems with leaking during the day.  We do use a Huggies or Pampers Overnight diaper because our daughter is a heavy wetter and has leaked through the Seventh Generation diapers at night.  Other than that we love these and love that they are chlorine-free.  We get them from Amazon.com's Subscribe & Save program...
