DS is 3.5 and if DH or I tell him to not do something or don't do what he wants DS starts telling us to go away and he doesn't like us. It's been going on for a month or so. DH thinks we should punish the behavior (naughty step) but I think we should try to ignore it. It really winds me up after a while. Not sure what's the best way to handle it. Any ideas?
