My daughter has recently become very irritable—she's constantly showing anger, screaming loudly, and arguing with us, even saying rude things. But she wasn't like this before. Since childhood, she has always been good in studies and other activities. She was admitted to a new school about a month ago, where the school hours are quite long. Both of us are working parents, but we try to spend as much time with her as we can. The pressure at the new school is also very high. She just turned 6. If someone could help me with this issue, it would be really appreciated.
