I've a 4 yr old ds with global developmental delay. His skills are at about the 2 yr old level, but I feel there are some inconsistencies that don't fit with just a delay. He's very cute, got a good sense of humour, is very loving but very single minded with no sense of danger. He has a vocab of about 200 words and is beginning to put three words together. However, he has never said his own name, or his sisters, nor does he seem to recognise his name, he makes up words ( cup cup is forklift) and seems to have no desire to be understood by others (he just doesn't seem to get frustrated), he will say words then never say them again (he said words at 2 yrs old that he has never said again), he generalises words (door is anything that opens, George is any boy) and he still doesn't know animal sounds even though we say goodnight to his animals every night and he loves them. Is this just a delay? I had a really difficult birth and was involuntary pushing without being monitored for several hours, the paed told the midwife off when he was eventually called. Any one with an opinion?!
