Third day of kindy

Today didn't work out so well. Again, Louka ran off happily to play, but at lunchtime I got a phone call saying please come and take her home, she's had a twenty minute tantrum (not the first for the day). When I got there she was happily listening to a story, then she calmly ate her lunch, but she came to me straight after and was pleased to leave. She says she gets "sad" when the teachers get cross with her, but she won't say why she disobeys and makes them cross with her.
