That is absolutely my mother on the right. She always has the brightest smile, even as a child. She looks about 4 or 5 in the photo, but that is the smile my son wears in almost all of his photos.
I recognized my aunt Debbie quickly too. (That is her on the left.) My mother has told me often that I favor her & now I see it.
My mother has told me many times, that prior to her mother's death, she made them dresses that looked alike or that were similar. (Which makes me want to ask my aunt or my mother if she made these too.) They look adorable!
