When you have someone working as a nanny, you should be able to trust that they will care for your child as instructed, even if they are family.

What would you do if your mother-in-law was working as a nanny for your child, but you discovered that she was doing some very inappropriate things?

That is what happened to the guy in this story, so he had to fire her and eventually call the police for her trespassing, but some people in the family think that he treated her unfairly.

Once you read what happened, it is hard to imagine anyone thinking he did the wrong thing. Read through the full story below.

AITA, I had my MIL trespassed after she entered my home and fired my babysitter.

I am a widower. I lost my wife (Anne 34) just minutes after she gave birth to our first baby (Sammy).

It was very generous of the mother-in-law to offer.

She had a difficult pregnancy, so I took an indefinite leave 3 months before she was due. Sammy’s 4 months old now and before I went back to work, I told my MIL (Sandra 56) about my plans and if she can recommend a nanny to take care of my daughter when I work.

She offered to do it (nanny) for free. I told her she’s free to come by anytime during the day if she feels uncomfortable with a nanny looking after Sammy but she insisted on doing it herself.

Things started off so well.

So, I said yes and gave her a copy of the house keys. She comes 30 mins. before I leave for work, and when I come home, she stays for dinner and leaves after putting Sammy to sleep.

Everything was fine for the first couple of weeks until I noticed that Sammy’s not feeding as much. Her formula’s barely touched. I asked Sandra about it and why Sammy’s not feeding well.

Wait…What?

She said she’s trying to breastfeed my daughter. At first I thought she was joking then I realized she wasn’t. She said Sammy needs to latch for a few minutes everyday to “activate” her milk production.

I almost lost it, I told her she cannot do that, and she needs to stop. She said she will, but I caught her again when I walked in my daughter’s room and she was forcing Sammy to latch.

The mother-in-law is having some serious issues.

I confronted her and told her she’s no longer my baby’s nanny. I didn’t ask for the key back as she is still welcome to come visit anytime.

I asked for a 1 week leave from work to care for my daughter and find a nanny. I found one but two days after, she never returned. I called her and she said my “Mother” fired her the day before.

This lady needs therapy.

I asked her to describe the woman and I was livid when I realized it was Sandra. She came in my house using her key and fired my nanny.

I was about to call her when she showed up and said a convoluted story like how I hired an incompetent nanny, etc. etc.

He needs to protect his child.

I told her to leave but she refused and told me she’s calling CPS because I am endangering my child. We argued back and forth before I called the police and she was charged with trespassing.

I know my MIL is grieving the loss of her daughter, I am too. But she crossed the line when she disregarded my wishes. She is very upset with me.

No, he did the right thing.

My SIL and BIL are calling me ruthless and I am now second guessing myself. Have I taken it too far by calling the police?

AITA?

What the mother-in-law did crosses so many lines that it is hard to imagine anyone would think it was acceptable. He needs to keep her away until she gets her issues figured out.

Let’s see what the people in the comments have to say about what happened.

Grandma should never be around the child again.

Grandma needs professional help, but until then, he needs to keep her far away from his daughter. Her behavior is unhealthy and unacceptable.

Putting the interests of his daughter first means keeping her away by whatever means necessary.
