I recently found out that i am pregnant with my second child. Ever since then, my 2year old have been behaving very weirdly. He have been screaming and hitting me despite me trying to talk to him in a calm manner. What is happening?

Actually two year old still do not quite understand about a new baby will be his/her siblings. Two year old still needs lots of attention and love. I think the behavioural changes is not due to pregnancy .. more to starting of "terrible two" or "horrible three". Eventhough I am not pregnant, my three year old son will also do the same thing to me (screaming and hitting). When I talked calmly to him, he will not listen. This is the stage whereby we really need a lot of patience.
