Oboe Art & Method

Martin Schuring’s book is the best out there, and the second half of it is all about reedmaking.

You need an oboist who can look at the instrument, the reeds, and the kid and give pointers with better info than we have online. See if you can bring in someone from a nearby university for masterclasses.

Also, high F is a pretty awful note to start with. I'd have her work through an actual oboe beginner book (NOT the oboe version of a band book) like this one : https://www.amazon.com/Student-Instrumental-Course-Oboe-Level/dp/0757982891/ref=pd_aw_fbt_14_img_2?_encoding=UTF8&psc=1&refRID=DX114R6SZ9MCBAZTDY5E with the help of a book about oboe playing like https://www.amazon.com/Oboe-Art-Method-Martin-Schuring/dp/0195374576/ref=mp_s_a_1_1?ie=UTF8&qid=1539131437&sr=8-1&pi=AC_SX236_SY340_QL65&keywords=Martin+schuring+oboe&dpPl=1&dpID=51x7aICx6yL&ref=plSrch

Edit : so far from your description, I suspect e and its secondary key are MASSIVELY out of adjustment, and D and its secondary are somewhat, too. Another reason to bring in a professional (check the local colleges; you might even get a professor for free, if they can get paid as college recruitment, or you might get a cheap grad student). A professional oboist should be able to adjust things and better narrow down any issues that will require a repair shop, whereas many repair shops are terrifyingly poor at diagnosing and adjusting oboes. Of course, the kid might just not have all the holes fully covered, or might be letting the F# key up.
