Congrats to your friend. Sounds like she's had a bit of a rough start.
The sugar water will be due to low blood sugar in the baby. Actually, expressed colostrum is better (according to research) but hospitals often have this policy instead. Does she have access to an LC at the hospital? (And I'm assuming she was planning to breastfeed?) If she's not with her baby and feeding him, then she should get a pump pronto, and get that colostrum into her baby.
Sounds like you're already doing lots to help her out! I hope she says yes to house cleaning and both she and baby are well and home soon.
