thanks for the support I think I have just been missing someone to talk things through as DH is just dismissing it at the moment. I have started record of the language Gus uses so his actual word and what it is in reference to and the frequency in which he says them, maynot help but it feels better to see his achievements written down rather than trying to think"...now what words does he say?" so far i'm up to 24 including a few small three word sentences, I know it will probably come down to more than just language but it feels better at the moment, thank you for your comments and support it is appreciated
