cut the hair or wait???

Amaris has never had a haircut. She has been wanting to cut her hair for a while now. She wants to be like her big sister in the worst way! We decided about 6 months ago that she can cut her hair when she has 10 inches of hair from where she wants it cut. You need at least 10 inches in order to donate your hair to locks for love. Well, Amaris now has 12 inches to work with. If we cut her hair it will be about to her shoulders. I don't know what to do.....I suppose we will call the shop down the street and see about an appointment. Her hair will grow back and if she can be a blessing to a child who has no hair then I think the time is right. I will post before and after pics when we do it!
