I have a little leftie, turning 4 this year. He was also behind on drawing as he was wrongly encouraged to use his right hand. We did see from very early on that he prefers the left hand.
He's got left hand scissors and uses them beautifully. It is a bit harder to teach them to cut, try to sit directly opposite her when cutting so that she mirrors your movements.
Take some extra time teaching her to draw circles and helping her to catch up.
Things like hitting a ball with a bat or playing action golf can also be problematic. Just watch her and help her to figure out how to find her groove with the hand she prefers.
