Rather than answer the direct question about the puzzling issue of the 
rqncid taste coming and going, I'm addressing other points.

Erika, I was wondering why the mother was feeding EBM from a bottle, when 
she was apaprently there herself, as indicated by the above sentence.

My concern is that boiling the milk destroys too much of the protection 
provided in human milk. leaving a baby at risk of infection in an epidemic. 
The babies who died in an epidemic in a special care nursery in Belgrade 
(former yugoslavia) in 1950-1960 were all breastmilk-fed - but it had been 
boiled. The babies able to breastfeed directly, though exposed to the same 
bacteria, were well.  Efforts to end the epidemic were unsuccessful, until 
raw breastmilk was used for those babies who were unable to go directly to 
the breast. The original article is in French:

1. Tassovatz B, Kotsitch A. Le lait de femme et son action de protection 
contre les infections intestinales chez le nouveau-ne. Annales de Pediatrie 
1961; 37: 285-288.

For those unable to access the original article I have discussed it in a 
literature review article:
2. Thorley V. Human milk banking to 1985. Breastfeeding Review 2012; 20(1); 
17-23.
