My sister has an Evenflo discovery infant car seat from my niece that is discontiued. I am trying to find her a replacement pad/cushion for her second baby. The only pattern Evenflo had was a very loud animal print.They said that I would need the specific cover to match the car seat. Does anyone think that any Evenflo infant car seat pad would fit it?? Or does anyone have some magic tricks to get stains out of car seats?
