Both my boys were 6mths when I started solids, Jack on the traditional mush and Ben is following baby led weaning.
Personally I would suggest that you look into baby led weaning, there are a few threads on here. It took at least 2wks for Ben to actually swallow food which is fine and it probably took 4-6wks for him to be eating a large enough quantity for it to change the consistency of his dirty nappies! You could just try putting your baby in the highchair when you eat and just giving them some of what you are having (e.g. bread, cracker etc), all they will likely do is play with it but they will start getting used to food, this is what we did with Ben.
This thread is great and has heaps of info
