I think I did it! Thanks to everyone who contributed, some I made, some were graciously edited and sent to me! She had more than 1 for each day and they really made a difference!
They were the Cherokee brand from Target. DD's came from Target and Walmart.
I am so glad I did all of the birthday shirts, it got a lot of attention and the birthday buttons are sized for adults, and she couldn't wear them on her shirts, they pulled the shirt down!
Thanks again to everyone who shared their designs!
