DD 16 months has a dummy, she uses it mostly for bedtime, or if she is teething. The last week or so she has been holding the bottom of the dummy shield in her bottom lip. Kind of looks like she is jutting her bottom jaw out. When I say, ''put your dodie in properly!'' she slips her bottom lip back behind the dummy shield, and sucks normally for a bit, then within a few minutes, the shield is inside the bottom lip gain.
Any experience/advice?
