It's really easy to rub stain into a scratch on a wood door and make it hardly noticeable. I decided against paint for my new kitchen without any children (much less five under five!) and no animals, because I knew there would be scratches and I knew I wouldn't like the resulting "patina". You can paint out scratches a bit, but it's hard with a factory paint job. Factory paint is more durable than brushed paint, but brushed paint is easier to "fix". So... how much do you like the white vs. how much do you hate bumps and scratches? Would you ever consider something as unstylish as melamine? As expensive as lacquer? Do you expect to move or redo your kitchen by the time your kids are in their teens? Or when they're out of the house? Or do you expect this kitchen to survive their childhood?

Trends come and go, right now dark wood is out, and so in your mind your home looks dark. You bought that home for a reason, you loved the wood. Learning to decorate around the more permanent parts of your home forces you to be creative and makes a more interesting space, learn to see it as an exciting challenge. The floor is too light and so is the ceiling. It is actually the lightness that makes the wood feel so dark. Look up craftsman homes. They are only wood; pay attention to the paint colors. I promise you if you paint it all the charm will be lost and the room will feel too big.

No but I would use a primer just to get good adhesion.

Absolutely. White toilet, and shower are the most popular right now. I have BM China White is a bathroom with all white. Dove White is very white while your other choices will have a hint of color and look nice with white molding and doors. If you do Dove White, what would be your trim? There are so many “whites” I just did BM Elmira White in my kitchen. I needed an update and wanted it to be pared with my granite and backsplash. Start understanding undertones and what expisure your rooms have. Natural light makes all the difference. Sometimes it doesn't matter as all the detiviatives look nice anyway. For example, we usedp BM Manchester Tan in quite a few spaces and it never disappoints. Shoji and Swiss Coffee have been popular for years, so you probably can't go wrong. Your bathrooms can certainly be other colors. Are you planning on only white tiles in all the bathrooms? We did our Florida home in a version of BM Simply White and my style is transitional. Bathrooms were painted other colors.
