Housework is so much harder when you're home all day. I stayed home for 3 years when my first was born, and I felt like I was constantly cleaning up. Turns out it was because someone was walking around behind me undoing all of it.
Now that I work full time, I find that the house looks exactly how I left it. I wake up earlier than everyone else, so that's the time I spend doing the last-minute tidying. (Clean out papers from backpacks, load the last few things in the dishwasher, put away the shoes that have started to accumulate near the front door).
Also, a one year old can help clean up toys- my 18 month old sings CLEAN UP TOYS at the top of her voice and dumps everything into the toy box. Make sure your child has an easily accessible place to put stuff, and start making him clean up.
