hi most kids have some form of 'comforter' maybe this is hers im sure shes fine. my daughter had a 'comforter' which was a bra

she used to rub the strap and suck her dummy

she didnt care who was there lol it was scruffy she wouldnt let me wash it lol it caused me loads of embarrasing moments especially when it was left lying around lol...and obviously you could tell it belonged to me at one time

take care
