My 20 month dd still does not sleep through. We have tried controlled crying and she was sick twice within 15 minutes and cannot bear to do it again (besides she now climbs out of bed and runs to the door - in her sleeping bag!). Also tried just letting her cry it out for a while(when she was in a cot) Can't think of what else to do. Am I being too soft? Any tips or do we just wait for it to happen??
