Having had some very odd days here for the last few weeks, and similar concerns about how to catch up on lost sleep etc, I think my advice would be to take each day as it comes. Maybe you can put aside what has happened and just tell yourself that you will start afresh in the morning.
Believe me, I know what you mean when you say that if you don't do things yourself, they don't get done as you would like....I am lucky enough to have a husband who is at home for a day each week doing all child care (taking 1 to/from school and then looking after 2younger ones) and it drives me crazy that he doesn't take my advice about what works and what doesn't...and then complains when things don't work as they should!! That said, I have to bite my tongue as I am very lucky to be able to share the childcare as we do, as it means that I can keep a meaningful job and work sensible hours. I'm sure your mum didn't mean to disrupt the pattern of the day and she probably doesn't realise the stress it has caused you.
Good luck tonight and tomorrow. I think we're through the worst with my littlest one for the moment, so I'm here if you need any help or ideas.
