Argh!

My son continues to wake us up in the middle of the night, often more than once. It is grinding on me. I feel tired all day. We've tried everything to get him to stop. Usually it seems to indicate a worry he has about something. We thought it was the worry that we would put him in some kindergarten without him having any chance to prepare or adjust. We addressed that and he stopped the wake-ups. Now he's resumed again. It's hard.
