Just start with one job at a time. Try not to think of everything that needs doing, but something that you can achieve while Peter is sleeping. Do you have a laptop, while I'm in the kitchen either cleaning it or cooking, I have my laptop on the bench. That way, I get my internet time and I'm doing something productive
First thing in the morning, while the girls are having brekkie, I usually put a load of washing on. When the girls have finished their brekkie, they'll usually have a little bit of tv time, this is my time to wash the brekkie dishes, get something out of dinner that night, and hang the washing out. When the washing is ready, I put it on the lounge room floor and I get the girls to help me sort them into piles. Emily (like Peter) is still a little young to do it properly, but at least I'm cleaning while playing with them. And it's kind of fun for them.
