My DS (3) has been with his CM for nearly 2 years, he loves it there but recently he is having issues with tantrums; quite minor and normal for his age, however the childminder says he is making her 'upset' when he has a tantrum and has started saying they can't go on certain trips if he has a tantrum; when it happens now it seems that our CM doesn't have a lot of patience with him. This is quite different how I would handle this but I find it really hard to say anything as I think the CM would get offended. My Lo at home now will say, I made her sad when I cried. Am I overreacting? How is the best way to raise this?
