Check out warm diets. I had a really rough first delivery where everything that could go wrong did and I had lost tons of blood. A friend from SriLanka of course insisted on helping the poor skinny American learn how to eat after having babies. She just knew if my mom was there she would have been showing me how to do it right. Anyway according to her after any major surgery, pregnancy ( anything really where there is blood loss and physical trauma) that you must eat "warm foods". Salad was a huge no no. I can't remember it all but I know she made a custard type thing to build me up. Something like a warm rice pudding. Chicken soup I know was part of it. I swear she put ginger and tumeric in everything. Its not that everything had to be warm really. It was something to do with essence but it was very nutritionally dense. I am sure you daughter needs everything she can get to recover. I hope she feels better soon.
