Negative Positive
Title: Just what we needed!
Review: We tried to stop our daughter's thumb sucking with Thum a few months ago. It worked and within a couple of days she stopped completely. But a few months later, she started sucking again, and when we reapplied the Thum, she sucked right through the bitter taste. Then we decided to buy Mavala. It worked like a charm and only needs to be applied every other day. There is no way she can keep her thumb in her mouth now.
