No need to 罵 lah!
We don't encourage 罵 in my family also. We encourage.
However, you should introduce some books to encourage your little girl about love.
My son, only 4, has two books: I love my daddy because... and I love my mommy because...
Also, we have a book: We love you because god gives you to us.
Make sure you encourage her about it.
Need to get back to work...
