Hi Reb-
with my girls...it always took about a year for their cycles to level out...I would make sure that she is not 'saturating' pads too often...and it is always a good idea to let your/her ob know and bounce it off of them.
I say that because I did have an issue with EXTREME bleeding several month after my first mense...I thought it was normal to saturate and change pads every hour. My mom did not talk to me about menstruation (left me a pamphlet and some pads). Anyhoo...she finally noticed ALL THESE PADS!! Took me to a doc...and all was well (after some meds to slow the flow).
SO...my suggestion is keep track of how heavy the flow is...and bounce it off the doc!!
Best Luck!
