K.,
Not only have I done a kitchen remodel with little ones, but I was doing in-home day care at the time. I'm not going to lie, it's a mess. I had to wash baby bottles & do dishes in the laundry sink. My biggest mistake was doing it in the winter. Didn't plan on doing it in the winter, but once we decided we were doing it, it took some time to get it up and running. We had different contractors bid on the project and then waiting for the permits took time. In the mean time, while we were waiting for the permits, our contractor had to start a new job so we were pushed back. Long story short, start now. Do your homework picking a contractor, loans, etc. If you start now you will be ready to go by spring. This way you can use your grill and be outside durning the mess. All the mess is long forgotten, & the day the kitchen was done, it all became worth it. My biggest suggestion is to make sure that you have a spot to set up a make shift kitchen. YOu will still need your microwave and a fridge. The dust is really worse than anyone could really tell you. Get rid of everthing on the same floor as the kitchen ex. no nick nacks, or wall decor, in any room on the same floor. No matter how much they try to seal off the kitchen, dust will be everywhere. It really is worth it and if you are prepared it's not that bad. Two years after the kitchen, I did a second story addition and we lived in the house during that as well. Good luck!
