I am feeling a little frustrated at the moment as my son has been having full blown tantrums. I understand that this is what kids do when they don't get their own way etc but lately it seems my son is tantruming for no apparent reason and there is nothing I can do to comfort him as when I do he tries to hit me. I got home from work the other day and he saw me and completely ignored me and then when I went near him, he threw himself on the ground and was inconsolable. he seemed tired but he had slept for 3 hours in the day!! He just seems so cranky - Is this normal behaviour for this age???
