Id recommend that you stop offering so often. Im counting 8 different ways of trying to feed in 5 weeks (assuming you didnt try any of those twice). Offering too much can actually do more harm than good. Keep trying different things if you like, but do not offer more than once a week.
Get a scale and weight her once a week. If shes not losing weight, dont worry. Ive had balls of all ages stop eating (for much longer than 5 weeks) and then just start up again on their own, especially this time of year.
