To reckon that, troll or not a troll, 90% on mumsnet on AIBU are as bad as eachother.
In real life the best thing to inflame an argument is to argue back. If a kid does something wrong that isn't life threatening, we ignore it and hope they don't do it again to get a reaction.
AIBU to think, everyone on AIBU has a pretty strong inner toddler tendency?
