Please tell me someone else has had this experience and it is normal. I just walked into the kitchen to find my ds2 aged 5 had locked his brother (7) in the utility room, had weed into one of those plastic lolly maker things and told his brother to drink it. They had just been fighting and I was trying to ignore them. DS 2 probably needs more attention or something. Anyone with similiar experiences or ideas of how to deal with this behaviour?
