Babies may be small, but the boundaries around them aren’t.

So when a mom stepped back after her sibling’s wasted fiancé tried to grab her infant despite being told no, he doubled down with jokes about her being paranoid.

Lines in the sand were quickly drawn after that.

AITA for refusing to let my sister’s fiancé hold our baby after he openly mocked my parenting in front of my whole family?

I (30F) have a 6 month old baby.

My sister (28F) has been dating her fiancé for like 3 months only. I’ve met him a few times before.

Yesterday we were at a family BBQ.

I was holding my baby, and he comes up, already kinda wasted, reaches out and I was like “please don’t touch him he been fussy today.”

That’s when this fiancé fully puts his foot in his mouth.

He literally laughs and says loud, “oh come on u overprotective. Babies cry u need to toughen him up.”

Then he tries to grab the baby while I was holding him.

I step back and he keeps joking, “stop being so paranoid, babies are easy, you’re just make it worse!”

No one could believe their eyes, but also no one came to help.

Everyone was like laughing nervously but I could tell they thought he was being rude.

My sister didn’t do anything.

I told my sister after the party he cant hold my baby at our house or at any family thing.

That’s when the sister took her fiancé’s side.

She got super mad and says I overreacting and I cant control people.

I feel like its about safety and respect not control.

AITA?

Protecting a baby is just good parenting.

What did Reddit think?

This man should be banned from all family gatherings after this little incident.

Any logical person would react the way this parent did.

It’s kind of a parent’s job to “control” their baby’s safety.

This family really doesn’t seem to know what they’re talking about.

This sister doesn’t seem to know a thing about parenting — or choosing good partners.

“No” isn’t a suggestion, especially when it comes to an infant.
