Negative Positive
Title: limited effectiveness
Review: This product worked great for a week but my extremely determined 3 year old is now back to sucking her fingers. The product is extremely bitter (I tested on my fingers first) and an instant deterrent, however, a bit after a week my daughter got used to the taste (I didn't) and would stick her fingers in her mouth a few minutes after I applied the product. I would ask her how her fingers tasted and she replied, "bad" but was determined to stick her fingers in her mouth anyway. Needless to say, we are now looking for another product.
Is the review positive or negative?
