(CNN) -- A Texas mother is outraged after she put a sweet note in her five-year-old son's lunchbox, only to get a nasty note from a daycare employee in return.
The incident has led to a firing.
The mother, identified only as Francesca, said her son has been going to Rocking Horse Day Care in Kingwood for three years and has never had any problems.
Francesca said she recently made healthy changes to her son’s lunch and wrote a note for extra support. The note in his lunchbox asked workers to "please tell my son that his mommy loves him so much and that I’m thinking about him."
That same note came back in the lunchbox that evening and had something new written at the bottom: "No! Put him on a diet & go away."
Francesca alerted the day care, who then investigated and told her the employee never intended for her to see what was written.
A director at the center said the employee admitted to writing the message and was fired.
In the meantime, Francesca said she is going to find another daycare for her son.
