DD is nearly 4, she doesn't watch a massive amount of TV, and is usually reasonably well behaved (pushes boundaries of course, but is quite rational).
But there are two TV shows that appear to have an immediate detrimental effect on her behaviour (taking it from standard nearly 4 year old, to actively and intentionally 'naughty' behaviour).
They are Peter Rabbit (which I hate anyway), and Messy Goes to Okido.
Am I imagining it? Or do some TV shows just make them behave Iike total rotters?
