When I was little my mom would always braid my hair, or pull the top up and put a big bow in it...
My favorite was when she put it in a low pony tail, then divided the hair above the rubber band in half, and pulled the hair below the rubber band through the hole. It made a fancy look, but it's super quick and easy. I forget the name of the style though.
I loved french braids too. And pigtails. And lots of bows!
I know you have four kids, so you might not have a lot of time for this, but if you want to give it a try you might. At Michaels ( or any craft store, I'm sure) you can get a kit for really cheap on how to make bows. Then you can let your daughter pick out ribbons she likes (really cheap) and she can help you make bows (it is actually pretty easy and fun! And it would be a great time for you to bond with her.) You can hot glue the different bows onto alligator clips (also available at Micahels/craft stores for super cheap) and you can put them in her hair with any hair style. They will spice up any pony tail! And alligator clips are great for really fine hair (my daughter is one and has very fine hair still and these stay in her hair great!)
Plus, alligator clips are really easy to use so she can put them in herself.
