My daughter’s daycare teacher keeps calling her by a weird nickname — I say it’s disrespectful

This mom is ready to go to the Mat-tresses.

One frustrated parent is calling out her daughter’s daycare teacher after they assigned her precious peanut a weird nickname the family has never used.

The miffed mama recently turned to Reddit to anonymously ask for advice on how to call out the offending parties — without causing offense.

The moniker mishegas began a week after baby Mathilda was enrolled in the program, user foolme1timee explained.

Soon, she noticed the teacher had given her bundle of joy a strange and unflattering nickname.

“When I went to pick her up yesterday her teacher said ‘Mat had a good day,’” she wrote.

“Thinking I might have misheard I brushed it off,” she confessed.

But when the mother returned the next day, she heard the teacher use the nickname again.

“I dropped her off today and they said ‘Ms. Mat will have a great day’,” the woman said.

“That’s when I noticed a few of her personal items labeled with Mat too.”

She explained that she and her family refer to the child as Matilda, Tilly and Tilda. They appeared bewildered that someone would just invent a new name for her.

“She spends 8 hours a day there and I really do not want her to get used to being called Mat,” the mother wrote.

The conflicted mother posted on the blog site to ask others what she should do.

“How should I approach this? Or do I just try to get over it?” she asked.

Most people agreed that she should “just flat out say: We don’t care for the nickname Mat. Please call her Tilly.”

“This is the correct answer. Do not be subtle. Not everyone recognizes subtlety,” someone else wrote.

This isn’t the first time that parents have turned to Reddit to ask for anonymous child rearing advice.

One dad recently asked site users how he should handle his son’s aggression, specifically towards his mother.

The fed-up father explained that his six-year-old has been the cause of stress around the house as he easily gives in to his intrusive thoughts, thus creating havoc around the house and everywhere he goes.

Parents online explained Alexander’s behavior shouldn’t be accepted and encouraged the dad to take action.

Others recommended seeking professional help. “Try behavioral therapy, not only for the child but in a setting for parents and child,” a person wrote.
