How to cut girl/toddlers hair?

As your child gets older its advisable to give their hair a little trim every now and again regardless if its a boy or girl. All my nephews have had their hair trimmed since they were very small, they ended up with very uniform and healthy hair. My daughter has been having her hair trimmed every month since she was one years old, her hair grows very quick! If I was to leave her hair she wouldn't be able to see, as well as trimming the front (fringe) I also do the sides and the back every now and again but not monthly as I do her fringe.
