I am sat here with a sleeping baby thinking how it is strange putting him to sleep with no dummy as I was so used to the 'routine'. Then I realised, his dummy use for sleeps was irratic in the first 10 weeks. Sometimes he wanted it, sometimes not. The only time he would have a dummy other than til he fell asleep was when we were out and about in town/supermarket.
I realise now that the increase in using it for naps and sleep must have been to comfort from the pain he has been in. He must finally feel comfortable falling asleep.
He never kept it in once asleep. But he definitely needed it for most sleeps in the last 6 weeks.
