We seem to have regressed.  She was up twice overnight, each time needing a small bottle to calm down.  We then got her up at the normal time.  First nap was normal, but the second nap went a little late.  When bedtime came, she went right to sleep, but only for a few minutes.  She wailed for about half an hour, but after a BPD (big poopie diaper), she went right to sleep.
