Time Management...?

The last few days have been so interesting as I have learnt some new recipes and plied Ruby with good food. She's loving it! 
She's sleeping better during the day now and also during the night, which she was already pretty good with but had started waking for a night feed again.
Today she slept really well so I was able to get a few things done, but with so many things on the list - what gets priority?
There is food shopping to be done, basic cleaning like dishes, clothes and heaven forbid, vaccuming. Cooking meals for me, hubby, Ruby and sometimes Rob who works here often.
Then there is the business. 

I opened my emails this morning and had a very narky customer (who is usually very positive and friendly) who said that her web pages had reverted to old content and that there were errors and it was ridiculous etc. I called her but she wasn't answering so I checked through the site and didn't find anything amiss except an old address on one page which I updated.
I had to duck out to get a few things and on my return I had a phone message letting me know from my client's assistant that there was one thing that needed changing.
So I fixed it up and sent an email confirming and asking for more details about which pages/what content had actually reverted, and to maybe check to see if she was looking at a cache file.
I haven't heard back.
I never like it when someone sends an aggressive message and then, possibly on noticing that there actually isn't anything wrong, doesn't even send a quick message saying it was now ok. I want my clients to have prompt support and to feel confident that their sites are working for them - but I need them to let me know what's going on at their end too.
It makes me wonder whether I should have prioritised the dishes after all!
That being said, I have some people I do work for and some who support me with work, who are simply sensational. The VAs on my network are inspiring, supportive of each other, caring and smart. The contractors who I have doing jobs for me are wonderful - they really know their stuff and they are always keen to find solutions.
I am thinking that with my new priorities, I would be best to focus on my network and to work on creating new sites (which I really enjoy and can do out of hours), rather than maintaining them, as I now know that I am unlikely to drop everything (being my child in particular) to update a notice that would have been updated long ago if the client had paid their invoice on time. Thankfully, I have people around me who are great with updates so forces combined, we can be Captain Planet!
