Which companies make soft silicone breast shields/breast pumps that are compatable with them? I'm always interested in trying new things. I currently use either Ameda lactaline with their flexishield or the softfit with Medela Swing. I do quite well with them but again always curious to see if there's anything better. I know Avent makes one as well but are there any others? How would you rate them? I can't use the hard shields, the hard angles feel absolutely atrocious to me.
