I work from home and know that having little ones around while you're dealing with deadlines is a major juggling act. Heartless as it may seem, it's best that aunty takes her business elsewhere. And good riddance too! Really inconsiderate to insist on updates on short notice and it adds a load of rudeness to wait until your on vacation. I've the same problem with my sister, who is working under the 'grandfather clause' that because I created and maintained her website for free the first year, that all updates are free forever. And because she's my sister, paying her hosting on time just isn't a priority ... I'll understand, right?
Like Bedlam123 stated, don't do work for relatives and friends. Unfortunately, we all learn this the hard way.

Glad you got through the ordeal and made your $200. ... Now you need a vacation!
