Thanks so much for all your responses. I may be panicking a little too much possibly... but this has not been the 1st hurdle and I can't sleep properly due to the suspense and not knowing, I am sure Welshpod in particular can relate to this!
Alot of other peoples children have had S & L therapy etc but the issue has only been brought up lately with my son so we have no real documentation or assessment or diagnosis just that he is behind with speech and he also was a little slower at walking it was about 16 months when he started to walk. I wish you the best of luck Welshpod, do let me know how you get on
