Hey , so I just would like a bit of advice. What were the early telltale signs that you child had autism before being diagnosed? My 20 month old is amazing , he walks he listens to what I say he reacts to sounds around him he waves goodbye and blows kisses and gives kisses and I believe he is developing well. But I do have some concerns.. he will hit himself out of frustration , he walks on his toes alot, he says around 2-3 words. He doesn't copy anything I say. I spend a lot of time reading with him and to him and do a lot of talking to him. He reacts but he just isn't saying many more than 3 words. I may be over reacting and thinking too much into things. But just really want some advice on what next steps I can take , or is this just normal? Thank you x
