End Of An Era....Felice o Triste

Today my youngest daughter started to crawl. She is not ready to enter the Boston Marathon but she is mobile. I am as proud as I am happy but what does this mean? Will I ever go through the first baby stages ever again? Will I ever feel the joy and frustration that is the first months with a baby with no mobility? Did I enjoy it and take advantage of it as much as possible?

I don't know and I don't know how that makes me feel. I am done with infants forever?

Catholic guilt is one thing but this is crazy.
