Dd1 never had a dummy and never wanted one.

Dd2 was became hard to settle and sleep was terrible at about 15 months. I offered her a dummy and she has been a dream ever since. It's purely comfort, but i give her a kiss, pop her into bed with a dummy and her toy, and she drifts off to sleep without a peep. It has been a savior and I attribute her fantastic sleep to the comfort the dummy gives her. She only has it in bed but I need to find a replacement soon as she's getting a bit old and I don't want to damage her teeth.
