RE: 2 week baby breastfeeding sometimes for 2 hours straight
If you are taking your prenatal vitamins and eating and drinking properly, I can't imagine that your milk is not nutritous enough! Mothers and MIL's tend to speak our worst possible irrational fears, I think.
How often are you putting her down for a nap or swaddling her and rocking/soothing to get her to sleep? Maybe when she is screaming after you have fed her plenty, she is actually tired. I know in the beginning I did not understand how long my baby could be awake without needing a nap, so that thought occurred to me.
Have you tried a pacifier?
