When a niece enters her husband's account, it becomes a father-daughter relationship. Tell me your opinion.

Just an account number. Why bother? According to what you said now, your husband said no to this account. In that case, let them settle down. However, they'd better get birth certificates and birth certificates. When the child is born, you can settle your account first, and when you move your account to your husband's account, it will be fine naturally. In this case, super-life should not be fined, because when you transfer your account, you don't know whether you are married for the first time or for the second time. If your child directly settles in your husband's account, it is super-life. If you have children now, don't register their children yet. When your child is born, register together and give birth to twins directly. The hospital can issue a certificate. As for the eldest daughter and the second daughter, most people don't look at your household registration book, so why consider so much. Since we are close relatives, let's get along well. If you help them, they will help you in the future.
