You love him/her more than me
When one child accuses you of loving the other more, how do you answer? Before I even had children, I heard an answer to this question that I will never forget, and will use when/if I ever receive this question.
I don't love him/her more, I love you each differently.
I will add an extension to the answer by listing the wonderful things I love about them.
I also make special "dates" with each child so each one has special
mommy time. Sometimes those "dates" are just "cuddle dates."
