I love our wool soakers, but they aren't that reliable for a long car ride, etc. (I did just buy a 'crat, so that may be better.) Do wool covers work better? I always go for the soakers b/c they don't leave any red marks, but perhaps I should try a wool cover. If you prefer soakers, where can I get a good one? Maybe mine are just inferior. Thanks for your help, experienced mamas!
