Contemplations of an overloaded mommy

Things I've been spending a lot of time pondering the last few days, in no particular order:

• Do I want to try crash-course potty-training, or the more gradual approach? (If I do gradual, I think Rebecca is ready to start, but I'm not sure she's ready for an intense level yet.)
• How should I respond to Rebecca's recently-surfaced "minor" disobedience (refusing to come when I ask, etc.)?
• Why can Rebecca identify several letters, but have absolutely no concept of colors or numbers?
• Which of our friends/relatives wouldn't be offended or disappointed if I only sent e-thank-yous for Christmas gifts, as opposed to hand-written?
• Is it worth it to us to pay someone else to help clean our house periodically? If so, how do I find someone who uses non-toxic substances to clean (like good ol' baking soda, vinegar, essential oils, etc.), and/or how much effort will it take to train someone to do this?
• How on earth are we going to get rid of all the weeds in our yard without using bad chemicals?
• What am I going to make for dinner the next few nights? (I'm getting tired of the usuals.)
• Do we have the right asset allocation in our retirement savings? (Steve was a little squeamish when I told him how much his 401(k) had taken a hit over the last few months.)
• How can Steve and I celebrate our 5-year anniversary in a few months (particularly, how far away and for how long can we go by ourselves, and with whom can we leave Rebecca)?
• Will I ever feel like I'm competent as a wife and mother?

Silly and/or serious comments and suggestions on any of the above will be entertained, with the understanding that they will not necessarily be followed. :)
