After marrying into the family, this brother-in-law didn’t just want to be a stepdad—he wanted to outshine the kids’ actual father.

His strange competition for “Best Dad” reached a breaking point when he was called a giant man baby for throwing tantrums about the kids’ relationship with their dad.

Now, he’s demanding respect from everyone, but maybe a reality check is more in order.

Check it out.

AITA for calling my BIL a giant man baby?

My sister has been married twice.

With her ex-husband she has a 10 year old daughter and an 8 year old son.

She is currently expecting a baby (6ish months along) with her current/second husband.

Second husband is brother-in-law BIL) mentioned in the post.

My sister and her ex-husband’s marriage ended during her second pregnancy in reality.

They were together for several more months in an effort to make it work but they were never really in love (I believe this is somewhat relevant later).

I don’t think they ever really liked each other but both loved the children they shared.

The marriage ended and my sister started dating soon after.

She met BIL a year after her divorce was finalized.

At this point the kids were 3.5 and 1.5.

Sounds like Sis went from “staying together for the kids” to “upgrading the crew for round two!”

Problems began when my sister and BIL moved in together after 6 months of dating.

BIL did not like seeing the kids dad around.

The kids dad would pick them up for his custody time, would show up to preschool plays and meetings.

Then BIL got annoyed one day when he found out my parents had run into the kids dad and spoken to him at random.

He said nothing for ages after my parents mentioned it.

Months and maybe even more than a year later when I think back on it, he brought it up and told us all how offended he was that we were still friendly with the kids dad and he said this in front of the kids.

Ah yes, because apparently, divorces come with a “no-friendship” clause for the rest of the family.

When my sister and BIL got married he became visibly frustrated when the kids wanted to invite their dad.

He wasn’t invited.

But he was annoyed that a 4 and 6 year old wanted their dad there.

BIL has this one-sided and self-inflicted competition going on with the kids dad for the role as their dad.

He has tried encouraging the kids to call him dad, has asked my sister to go to court and get Father’s Day split/shared or alternated in some way so he can have them too.

I believe my sister allows this because BIL is the first man she has been in love with.

And she’s letting it blind her.

Nothing says “healthy family dynamic” quite like competing with a 6-year-old’s idea of Father’s Day.

BIL complains frequently that the kids treat him like a stranger or like a teacher they have to respect but don’t like.

Yesterday was my other sister’s birthday and we were at her house.

My sister’s kids were telling me about their dad and what was going on with him when BIL demanded to speak with me and tore me a new one for disrespecting him with talk of “the competition.”

He told me HE is my sister’s husband and the kids real dad and I should stop the disrespect.

I told him to quit being such a man baby and accept that he has stepkids and they have a loving father and that others are allowed to be on good terms with their father.

Sounds like BIL needs to take a break from playing “World’s Most Insecure Stepdad.”

He called me some names and said I owed him a lot more respect then I was showing him by saying that to his face.

AITA?

Needless to say, it sounds like BIL’s quest to win “Dad of the Year” is overshadowed by his knack for acting like a kid himself.

At least, that’s what Reddit thinks.

This person thinks BIL is a bozo.

This person says BIL shouldn’t even be allowed to be doing what he’s doing.

And this person says to watch her back.

BIL’s trying to out-dad the real dad, but he’s only winning in the whining department!

No one wants a guy like this around.
