My DD is generally not too naughty and I'm quite strict with her. She's 2. I do shout loudly if she does something naughty, but when I do it now (it used to just make her jump and stop whatever she was doing) she bursts into tears and gets upset. I am a bit scary and obv need to tone it down a bit. She was playing with her playdough and cutters today and then suddenly swept all the cutters onto the floor. I leaned down to her and said no very loudly and then said we do not throw things on the floor (something she does to get a rise out of me I think). She started crying.
What is the best way to show you are serious, being stern, to make it clear that the behaviour is not appropriate and that it makes you cross? Without being SHOUTY?
