My 26mo couldn't kick off her bad habit of sucking her fingers. Any successful ways to stop it? There is once when she gotten hfmd and we thought she wean off, but once she recover she start sucking again. Day and night! Now we need to bandage some of the fingers when she sleep cause her fingernails are getting weak from all the saliva soaking. . Sucking fingers is actually her way of self soothing thou. Sometimes when we don't let her suck she will bite her blanket. But it's still not a long term solution. Thanks!
