DS1 started preschool in Jan and I am at a loss as to how to deal with him now. He has always been a normal robust little toddler, but loved being at home with me, was naughty sometimes and had tantrums, but quickly got over them. He loves his preschool and his teacher and can't wait to go every morning, but when he gets home and at the weekends I don't recognise him. When I ask him to come here, he often says 'come here yourself' and 'don't you DARE tell me off', he deliberately does things he knows are not allowed. he is much more inclined to push and hit his friends and brother than before, and time out and the usual discipline seems to be water off a ducks back. He humphs like a teenager and glares at me and is obsessed with pretending to kill people, baddies, guns, shooting (not from anything at home - we are still at the cbeebies only stage). I have been into chat to his teacher about it, and she is amazed, says he is an angel at school. So, has he run out of the ability to be good by the time he gets home? How do I handle him? We are going through a real upheaval at the moment - 3rd baby due in 3 weeks, daddy in the Army and has been away for 2 months, and due home in 2 weeks, and a house move in 6 weeks. A lot of his friends have just moved as well, and I am sure all this plays a part, but tbh, I thought I would have at least until reception before these problems started to loom on the horizon. I know I can't wrap him in cotton wool, so how do I play it? (sorry for such a long post - well done to anyone still reading!!!)
