She's a pretty girl and you both will learn things together. I have owned horses for all my life, but never had any younger than 10 and untrained. Three years ago my sil talked my into taking her 3 year old saddlebred. This horse was afraid of everything and would walk right over you. She had no manners or training what so ever. Except for bathing her in the summer I can do anything with her now. Her ground manners are almost perfect. I can stand with her for hours and she will just doze off. I have even started saddle training her with some help and everything is going smoothly. My advice is to take things slow and repeat things when necessary. Even pick up some books on basic training. Best of luck.
