Mab, dont worry about the no dummy issue my first was the same he would not take a dummy for anything (not that we needed it) but once he started teething he took it and still has it now (but I could take it away permanently and he'd be fine without it). So Scally may be the same, sheesh that dummy has been a lifesaver with the teething!
Rips sometimes takes a dummy but spits it out after a min or two and then gets cranky. Guess he's going to be the same as big brother.
