I have a bit of a problem with my 5 year old son losing his temper over silly things that dont justify such actions.As the younger sibling he does the whole teasing his sister to the limits and reacting badly when told to stop or is disciplined(past the naughty step stage and persuing a smiley face chart instead).We are also facing problems with my nearly 9 year old daugter with terrible bouts of jealousy in any aspect from the smallest things,this in turn can lead to anger and confrontation mainly with her mum but also with myself and other adult family members if there.Please explain what we are missing if anything because we spend every day with the children doing various things as a family unit to one on one quality time with each child(swapping children on different days).We have implemented a treat system for good behaviour at the week end,but also have a great family active week in place also e.g baking,games,rollerblading.Even after all this we still cant over come these issues,HELP US UNDERSTAND.
