Hi Jenn,
I would give her a few months to see if it normalizes. Many times it's the body just trying to figure out the right balance. You may want to consider having her take an iron supplement if it continues to be heavy to prevent anemia.
In regards to pads, have considered trying cloth menstrual pads? Fresh Moon pads are super absorbant and made out of hemp and bamboo. They are super nice and comfortable. Because it is cloth, she will feel like she is wearing her underwear and not feel sticky or bulky.
Some women have serious reactions to the chemicals in pads and the body will bleed heavier to flush out toxins or the pH balance can get thrown off and create yeast, bacterial or odor issues due to the disposable pads.
I would never recommend tampons to any woman. Disposable products are not always sanitary, plus by pushing all those chemicals into the body where you are bleeding, you are allowing a direct access for them to enter her blood stream.
The other issue is that the rayon and other fabrics can create tiny ulcerations along the vaginal wall as well as the plastic applicators. Cell peeling and tiny ulcers have also been associated with tampon use.
Alternatives would be the Diva Cup or the Keeper/Moon Cups. I love the seasponge tampons as they are super easy and comfortable, but they need to be changed very frequently during heavy flow and I find that public bathrooms at schools rarely have a toilet and sink near each other where she can discretely clean it.
The best option though, would be for her to try the All In One's (AIO's) in the 11" size they hold a lot and if she needs more protection there is also a 13" which is a great option for nighttime.
To wash them, simply rinse them in cold water in the sink right after using them. If there is a little staining, spray some Bac Out and/or sprinkle a little oxygen bleach on them and then throw them in the laundry hamper. They can be washed and dried like normal.
