Hello all, 
Danielle, in spite of all the comments suggesting that she should have had a PEG tube, I'll be contrary.  
PEG tubes are NOT required for all! 
They can produce negative side effects themselves.  Lastly, there is a significant benefit to using the swallowing equipment we are born with.  Reliance on a tube for feeding can be a little too easy.    
Don't loose sleep wondering if her doctor missed this one. If he is watching her closely, the amount of weight loss she experienced is likely within a safe range.  
The good news is she should notice improvement (in little increments) in the next week or two.
