I'm a single mum to a 13yo DS. Just (3 weeks in) started work again following a few months off after redundancy. My son sees his dad regularly, he's on shifts so one week he'll be there for tea 3 nights and the next week only one, then every other weekend. My new job starts at 7.30 and I work until 4ish (sometimes later). This post was prompted by the fact I got in from work at 5.30, and didn't actually finish clearing up after tea until 8.00. Where did those hours go??! 
At the moment it feels like all I do is house jobs, admin, cook and get ready for work. I do have a cleaner so all I have to do is keep on top of tidying up, plus washing and ironing, and do the gardening but that 2.5 'lost' hours has me thinking. All I did was empty the dishwasher and tumble drier, make dinner (chicken kebabs and rice, and omelette and salad), make tomorrow's packed lunches (salad, plus cheese sarnies), eat dinner then clear up after dinner. I've got a whole heap of other stuff I meant to do but didn't get round to (ironing, emails etc). I just don't feel very effective.
And now it's gone 10.30 and I should be asleep!!
What tips and tricks do you all have to create a bit more time, or to get things done?
