Hi Candle, my kids are 14, 11, 8 and my youngest is just coming up to 16 months, she's a little ball of mischief and I can get very little done when she's awake, she just trashes the place and throws food everywhere. She has two 1 - 1.5 hour naps per day though so I manage to get most of my stuff done whilst she sleeps and I occasionally stick peppa pig on for half an hour to distract her so I can cook, etc. It is hard work when they're little though isn't it as they demand your attention all the time.
One tip I do have though is to stick them in the bath and clean the bathroom while you're in there watching them. She plays happily in the water while I give everywhere a wipe over then I just rinse the bath tub out when she gets out.
I also sometimes stick her in her high chair with some crayons and paper and let her scribble while I wash up and stick the washer on.
From my list today all I managed was to wash the dishes, cleaned the kitchen, tidied the living room half a million times, bought dd2's new pjs and socks for me and I swept the floors then took dd3 to the park to run off some energy.
I didn't get much else done as I had to go into town to the phone shop as Ds has yet again smashed the screen on his phone so I had to hand it in and claim on the insurance for a new one - honestly, he only got his last one replaced literally 2 weeks ago!! The £15 for a years insurance was definitely money well spent! Clumsy bugger.
