The first lesson I’ve learned as a trying-to-be-organized parent: you can never have too many flat surfaces. (Preferably out of reach of toddlers on tiptoes.)
The next lesson is to be ruthlessly realistic about what you can accomplish in a day. I’d rather feel bad at the beginning of the day, when I’m plotting the single thing I’ll accomplish post-baby bedtime and wishing it could be five, than right before I go to bed, when I see a list of four un-done things and feel bad.
That said, my parents visited over the weekend, and I was amazed at home much I got done while they were watching my son. No doubt I’ll talk about it for years.
