Today for about the 3rd time in a row when I went to pick up ds1 from nursery they "had a word" about his stubborn behaviour. He is very stubborn at home as well, though I've found ways of dealing with it, but how do I get him to not be stubborn when I'm not there? Is this normal at this age, or should the fact that they keep mentioning it to me be ringing alarm bells? Anybody had a similar experience or have any tips with how to handle it?
