Before DS was born I swore I wouldn't be using a dummy but we cracked one out the night we came home from hossy and it was a life saver. Without something to suck on (me, finger, DPs finger, fingers) he just cried & cried and came home from hossy all hoarse & croaky. He sounds a bit like Freya hun, in those first few days / weeks he could have sucked his way to China I swear (all normal off course) but my boobs were wrecked and often it just helped him settle off to sleep and give me a break. And funnily enough he spat it out at about 9 weeks old when he had a bit of a snuffly nose and never wanted it again, so it might not always be a long term thing for some kids. He had started to self-settle a little bit around the same time too.

If it were me in your situation with b/f established I would give it a go - if only to reduce the risk of nipple trauma for you, which was our downfall. We didn't suceed at b/f because my nipples were so badly damaged in the early days and just didn't recover.

From memory we used a NUK dummy.
