Can anyone change the age on this for me?

[momom]

We are going to 1900 Park Fare for dinner and my daughter would love to wear one of these designs but it doesn't look like Tinkerbell is designing? Can someone else change the number on this to 12? It is found at

and this one to say "Today is my 12th birthday". It is found at

Any help or advice is really appreciated. Thank you so much.
