Our apartment is 950 square feet and is, of course, completely  baby/toddler proofed.  We have books, toys, and games for children aged 6  months to 4 years.  Some favorites include our play kitchen, many  wooden toys and art supplies, and of course our train table (you know,  the kind that kids are always so drawn to and are impossible to pull  away from in toy stores!).  Duplo is also a huge deal around here lately, especially the Duplo trains.  We do not have cable or watch television during the day,  although we do have a large monitor hooked up to a computer for music  and the occasional movie in the evening once the child care kids have gone home. 
There is a private child's play area in  the back and it's only open to people who live in our building. There is  a sand box, some outdoor toys, and a small slide.  It's the perfect place to  use bubbles, sidewalk chalk, etc. 
We do not keep toxic chemicals of any kind in our home.  The only substances we use are ones that could be  safely swallowed (by either the dog or by our child) so that includes  our cosmetics, hand soaps,  laundry detergent, dish  detergents, cleaning products, etc.  We also don't allow the carpets or any surfaces to be cleaned by any suspicious substances.
The safety turtle  that I am, I have the house completely, 100% child proofed, from  covering the plugs, to keeping cords out of reach, securing bookshelves  to walls, and ensuring that the drawers in the house are child proofed  as well. We have screens on our windows and the windows themselves only open 4 inches.  I always operate with the  "better safe than sorry" mentality.  Part of the process involved in becoming a Registered License-Not-Required child care provider includes a home inspection and safety check as provided by the West Coast Child Care Resource Centre.  We also keep an emergency kit on hand that has enough food, water, and resources for our family and all the child care kids in the event of an earthquake.  
All these things considered, the  bottom line is, I'll be playing with the kids and giving them my undivided  attention 100% of the time anyway. 
One last thing I want to be very  open about: we have a 10 lb yorkshire terrier (Max). He's basically the  most docile and gentle creature ever, but I know that some people are  nervous about having their kids around dogs. Basically, Max actually  doesn't even care if children or other dogs touch or take his food,  he's that gentle. I absolutely have no concerns about him being around  my own son and I'm certain he wouldn't be aggressive at all around any  person or other animal, even if they were to pull at his fur or try to  take his food.  Most people who have left their children with me have actually seen having Max around as a plus for their children since they don't have dogs themselves.  Max has never given the children any trouble; every once in a while a child isn't gentle with him and when that happens Max just goes in the other room and happily sleeps.
