I hear ya! It's so rough because you want to be with them every minute!!
So - be with him every minute you can!
There are some usefull tips on www.flylady.com - take what you can use from it. For example - 2 loads of laundry a day. I usually will put one in when I get upstairs to spend time with my daughters. THere's enough time to start a load in the washer, move it to the dryer and start another load. After the kids are asleep, and about the time I'm ready for bed, it's time for another. In the morning, once more...you can usually get a couple loads done that way. After the kids are asleep, fill up the dishwasher and run it. If there's time, unload, but otherwise it can wait until morning.
From the time we get home, we spend about 3 hours with our girls before they go to bed. And the other stuff we do what we can, and "make peace with imperfection" because it's more important to spend time with our girls than it is to have everything spotless. When he gets a little older, he'll likely want to help too - my 4 year old LOVES to help with the laundry. I'll tell her what to throw into the washer, and the liquid is in a "squirt bottle" - 1 1/2 squirts per load, and she loves to do it and then start it up.
Good luck!
