Harmony is growing so fast

I can't believe that Harmony is already 4 years old! It is so scarey. I feel like just yesterday she was a brand new little baby. She has learned and grown so much. My little princess has been through so much! Being a single mother has been a long rocky road; but I know deep down it is for the better! It has been so hard and sometimes I am scared that I am setting Harmony up for failure. I left her father due to not wanting Harmony to think it is okay to be treated the way i was treated and to live unhappy! We were miserable. Harmony has had a very hard time with the transistion. She misses her daddy! She does she him once in a while; she has started understanding why her father and I are no longer together. I know that when she gets older she will realize why i did what i did... Just the process of her growing and maturing has been and will be tough. All i can do is live one day at a time; stay strong and teach my little princess to be a very Independant women.
