the contoured shape of these burp cloth make they the most effective of any burp cloth I have try , they stay in place and they be so soft ! they also come in such cute pattern . I buy one of these with my first baby and I immediately want to replace all my burp cloth with burpy bib . as a bib , it can be a little bulky , but it be nice to have in a pinch and I always appreciate a multi-tasker in my diaper bag .
