Here is my routine for my house if I really, really want to get it clean.
For the walls (because no matter what, troddlers with dirty hands, touch the walls and muck them up) I use the "Magic Eraser". Just saturate the pad, wring it out and begin to scrub the dirty spots. It gets walls clean like magic.
Also, the carpet. Check for horrific stains that would immediately catch the eye. Try to stain treat them first and overall give it a better looking appearence. You can then use "Fresh Linen" Glade carpet powder before you vacuum very thoroughly to make it smell nice and fresh.
In the kitchen, use clorox for the counters, stove top and walls behind the stove to get any grime off and give it a sparkling, clean look as well as making it smell fresh. You can use Pinesol on the floors in the kitchen and bathroom as well. Which is good for disinfecting and also, the smell is fresh.
Make sure all the dishes are put away and the washcloth and soap are nicely laid out on the back of the sink. Organize anything you might leave out on the coutner (spices, coffee making things, utensils, appliances) and also be sure things like the toaster and microwave are cleaned out as well. The next step is cleaning out your refridgerator and pantry, which have a knack for building up quickly with unused items that are easily forgotten.
Now for the bathroom. Mirrors and walls surrounding the sink, be sure to clean thoroughly for any toothpaste splatters, make up or little grooming hairs. Organize anything left out on the sink (toothbrushes, soaps, hair products) and the same goes for the mirror/medicine cabinet. Put things of the like in proper places together in the cabinet. Organize any under cabinets you may have (cleaning products on one side, make-up, pads/tampons, extra rolls of tp on the other.
Wash your towels and dry them with a dryer sheet to make them smell really fresh and organize them neatly on your towel rack (to make a nice pattern of some sort but nothing overdone or gaudy)
Wash your shower curtain and replace the plastic liner. Clean all in and around the toilet to make it sparkle.
Toddler toys. Organize nicely and make sure all toys with pieces go together (blocks in the box - none left out, any stuffed animals get put together, etc etc).
The livingroom and dining room, just be sure any unnecessary clutter is cleaned up and organized. Clutter is a HUGE factor in a house looking neat, organized and clean. Don't leave mail or any papers on the tables that do not need to be there. Dust any coffee tables, end tables or furniture that can collect dust. Windex any windows, pictures, t.v or mirrors in that area to make them sparkle. Organize movies, dvds and CD's. Use frabric Febreeze on couches, chairs or ottomans. Fold and lay out any throws or blankets nicely (draping them over a chair or folding to it hangs over the back of the couch)
In the bedroom, I'm sorta out of options for you there because that's my weak spot. Haha, just organize and put all clothes away and make the bed.
Lastly, a house can look nice, but if it doesn't smell nice it ruins everything. So up high on a shelf where baby can't reach, you can light a candle or two. However, once you clean with all these products, your house should be sure to smell fresh. And, when it's cooler out, I like to open all the windows to get a nice breeze through the house and air it out briefly.
Making lists are REALLY good too. It helps me see what has been done and what hasn't.
Phew...ok, that's my cleaning routine and I hope it helps!
