My son is 16 months old and will not talk. He has always been able to say mumma and dadda from an early age he sat up early walked early but has not yet got the hang of talking. All my friends babys can say words like ...bus,bye bye,peoples names and things but my son just won't do it! If i ask him to say bye bye he just starts waving ! He knows what words are but wont say this i just wondered if this was normal at 16 months as i am beginning to get a bit worried as many people are picking up on this! getting me down a bit i suppose! any advice or help?
