My dear son,
We are blessed to have a nanny to take care of you while Mommy and Daddy are at work. A nanny was the best decision for our family and for our work schedules, even with me working a reduced schedule, and we really like our nanny. However, my darling son, please don't like the nanny more than me. Some people try to calm my fears and tell me that this is not possible, but for this new mamma it's a real-life concern and the thought hurts my heart. So bear with my (possibly irrational) fears and please don't like the nanny more than me.
My undying love,
