My fantastic generally well behaved elder daughter seems to have found a trump card to anything we can do to control her behavior. Shes not naughty very often but when she is we are fans of the naughty step followed by a quick discussion of what went wrong, that she isn't a naughty girl but the behaviour wasn't good enough, cuddle and kiss, 'All over, lets go and look at a book' etc... nothing too scary there. DD has realised however that asking her to stay on the stairs for 2 minutes is boring. She immediately asks for the potty. We realise this is tactic but allow her to use the potty. She may or may not go but when she says she has finished we put her back on the stairs. Cue fury and another demand to use the potty. This goes on for a bit until she just stops asking for the potty and wees on the carpet. . This is annoying enough but having been a fantastic sleeper for well over a year she has started waking up in the night and asking to play with her toys. We say no, its night time, no fuss, keep talking to a minimum and leave. She asks to use the potty... we provide it.... she may or may not go... this goes on for a while... but she has always got some left to wee on the duvet. We have tried confiscating toys but she has so many and no particular favourites so she just plays with something else - we tried confiscating the lot and she just flicks through magazines or sorts shoes into pairs or size order or folds towels as neatly as she can - I cant bore her enough to realise its a punishment without making her sit still and do nothing. Shes two and a half. Potty trained herself at 14 months by watching a little girl at her childminders and hasnt worn a nappy at night for 6 months.... what to do? put her in one before putting her on the naughty step? put her in one at night? our stairs have the feint wiff of a nursing home now and we have no idea how to gain the upper hand again any ideas?
