I am a SAHM with a 3.5 yr old,a 21mth old and a 5mth old. I have concerns over the 21mth old as I am not sure if he understands me, he is a very relaxed and easy going child most of the time, eats what you feed him and sleeps through the night, in most ways a dream baby... but I have trouble engaging with him. He is very focused on certain things and determined to do these things over and over. He shakes with anger when things do not go as he wants them to and when I try and talk to him I have no idea if I am getting through to him. I have had his hearing tested and it is fine. On the flip side he plays quite well with his older brother, he ignores his sister but I think its probably a bit of jealousy as she has taken his place of the youngest in the house. Does anyone have any suggestions of games to engage him with?
