I thought it didn't because it doesn't say so on the box. I had ordered them because of the Amazon deal and opened the box on Monday. Tonight I noticed my DS is getting a rash on his butt, which is highly unusual. It is really red. Would it take 2 days to develop a rash if the diapers didn't agree with him? I guess common sense would tell me the diapers are the culprit. But we used some cruisers w/drymax before and he didn't have a bad reaction, I just decided to switch to Up&Up. I guess I will be Freecycling this huge box of diapers. I just don't want to chance it getting worse. Good thing they were so cheap! No more Pampers for me, ever.
