We introduced a dummy at day 5 and she didn't have any nipple confusion or anything like that. If anything, it saved me from nipple damage because she was comfort sucking all the time.

Sophie - 2 weeks sounds like plenty of time!

I love dummies. They really really help X to settle just before bed. However, I dtry not to use them any other time, because I want to hear her cries and cues. We are going to try and wean the dummy off her by 4 months, but I don't care if she has one until she is 3. They work so well for us .

DD1 will take any dummy now, but the first one she took was the happy baby brand.
