so my son is 3yrs old and i really need some advice. my first issue is that he doesnt talk yet. he will kind of babble and scream thats all he does, and on top of that he doesnt really seem to understand allot of what you say to him. it more or less seems like he is ignoring me. we have had his hearing tested multiple times and it is fine. any one have any ideas? also the second thing i am worried about is that he is very violent towards myself other kids and to himself. he will kick bite pinch and even try to choke you. this really worries me . i have no idea what to do. we have tried time outs, we have tried getting down to his eye level and talking to him, but so far nothing is working. i really dont understand because he has never been in a violent environment or anything. but he is out of control . can anyone give me any ideas? and finally i am also worried about the fact that he is not potty trained yet. we have tried and he refuses. so we really have allot going on right now with him. and whats making it worse is his 2yr old sister is starting to copy him. so yeah if anyone has some ideas on what could be wrong with him or what i can do to help him please let me know .
