Your LO sounds very much how my LO was when he was non verbal, he would just point at things and get very upset over me not knowing what he wanted. Although he is talking now they say he is talking at the age or a 2 year old rather than a 4 year old ..I totally understand how you feel about if he was your first he would have been your last baby, this is pretty much how I feel although I would love another child, a baby takes up alot of time and with LOs temper, tantrums, laughs and tears, i have a pretty packed day!! The speech therapy waiting list was 18 months long in our area, and the appointment was only once a month.. However we decided to let him play on the iPad on number and alphabet games these helped him massively in bringing along his speech, the speech therapist said they were a great idea and childrens abc YouTube videos there very catchy and bright coloured so can keep a child interest whilst helping them learn. A special educational needs teacher also goes to the nursery every 2 weeks to check on him and how is he with the other children and developmentally as he will only play along side another child but not actually with them...he is VERY obsessive over trains ?! And being clean?! Is your son like this, is there anything that he will play with over and over again? My son will share any of his toys but god help if anyone touches his trains that he has lined up xx
