I went through the same thing with my son and ended up switching to cloth diapers when he was 9 months old. FuzziBunz and BumGenius are both great and easy to use cloth diapers. You can read about my experiences here - http://www.ladyexpatblog.com/search/label/cloth%20diapers.
Pampers were the only diapers that did not leave a rash or leak but then I started having to change the sheets 1-2 times a day and was tired of it. Good luck!
