First I want to say, can anyone point me on who to talk to or contact if I need to get him assessed?

Some days I feel he’s okay, others I question if he’s different..

He’s three, he was always a good baby, he never cried.. he started saying mama and then he stopped, but he’s just started saying mama again, he says train too, and yes and no, and dads and stuck, and help.. he doesn’t speak in sentences though, which I think is different for a 3 year old because my 1 year old talks more then him.. he tries to talk but it’s gibberish.. and when he gets frustrated he will scream to the top of his lungs, he doesn’t know how to play with others, he pushes and takes things without asking or any remorse if anyone is crying because of him, which I assume is normal toddler behaviour, and please don’t judge me, he is my oldest child, so idk what’s normal or not, and it’s been hard to get him out there during a pandemic, he was in daycare for a few days till it closed down..

He does line up all his toys too, or piles up all our stuff in a corner like just random stuff like chairs and toys and pillows and blankets.. he has no sense of danger, when we go for walks he just runs, he doesn’t walk, he runs until he starts coughing and puking, so I got a toddler leash for him, he walks to the road not sensing any danger of cars or other kids on bikes, he falls purposely sometimes too, he jumps off high places so I always gotta keep my eye on him, when he’s talking to someone he goes right in there face looking them straight in their eyes, and he will literally shove things anyones face to show what he has,

I also must add that we fled domestic violence when he was about 18 months old, he watched his dad beat me up and his dad would hold me down and let him hit me too.. and would get drunk and scream at us and held us at knife point and threatened to hurt the babies.. but I didn’t think he would remember any of that, because he was 1.. but that’s dealt with, he’s been charged..

Does this seem like normal toddler behaviour for a three year old?
