You are a good mother, so it is very wise not to discourage blindly ~
/kloc-about 0/4 years old is the age of "Seeds of Love", and his hazy affection for the opposite sex is also increasing. As an elder, parents personally do not recommend that you choose to suppress your daughter's contact with the opposite sex and give her various punishments. Children of this age are rebellious, and too much bondage will only lead to their stronger rebellion.
Then my personal opinion is:
1. Get to know your daughter's lover first. If the other person is not a particularly poor student or a gangster in society, then you don't need to interfere too much.
2. Be earnest, chat with your daughter kindly and ask her thoughts and expectations. In this way, I think you will find that your daughter is not that naive. She should have her own opinions and goals. You can agree to her contact with the other guy and her first love, but tell her it's best not to affect her study, and pay attention to her discretion, and don't allow the other person to have too intimate actions to protect herself.
3. Then, the psychological changes of boys and girls during love are very subtle. In the future, you need to pay more attention to your daughters and understand their inner world. Only in this way will the gap between the two generations gradually narrow.
