I've just spoken to our health visitor who has instructed me to get Ds into more of a routine and to use controlled crying.
I would not use Cc, although I have no issues with other parents doing this. We let Ds fall asleep on us and we put him in his cot when we go to bed. This works in our family and I don't see why we would change it at the moment.
Hv thinks as Ds doesn't go in his cot for naps and in the evening it may be contributing to his head butting? She seemed to think he has no routine, he does.
