Q: For the past several weeks, our just-turned 3-year-old has been waking up and coming into our room at all hours of the night with the usual excuses: He’s scared, hungry, thirsty, lonely, can’t sleep, has to use the bathroom, wants a kiss and so on. He goes to bed at 7:30 p.m. if he takes an afternoon nap and 6:30 p.m. if he doesn’t. We are a marriage-centered household, so evenings are for Mom and Dad.
