Husband left 8mo. unattended in high chair at hotel breakfast

Does he often do things like this

I don’t think anyone’s the arsehole here. I don’t know the background to your relationship, but just based on what you’ve written sounds like your husband resents you and finds you patronising. His response is childish, and you’re not wrong in advising him not to leave your baby unattended, but maybe it’s the “caught you” like you’re the parenting police that pissed him off?

My coparent is a sensitive Susan, so I have to reframe things so they don’t come off like criticism.

Maybe he was keeping an eye whilst grabbing fruit? I sometimes do this if I need to grab a bowl or cutlery.
I wouldn't leave her if she's completely out of your eyeline.

I mean that could’ve just been a teaching moment. He probably felt attacked with the “caught you” comment… but if he reacts often like that to you saying anything then that’s one thing.

This an easy fix and no reason to let the vacation be ruined.. just be like look “you left our baby unattended in a public setting” (fact) … state how it made you feel (fact) … “maybe next time we can communicate better so that we don’t have to leave him alone and everyone can get breakfast and be happy”
Let him know you weren’t trying to attack him rather bring it to his attention.
But if he’s a crybaby… save your breath and let him be mad. Don’t leave your kid alone 🤷🏾‍♀️ (I too have went to the buffet and stepped away from my child in high chair. My husband and I had this exact thing happen but I was in the wrong obviously)

It’s kinda hard to judge if he was wrong here. It might feel more serious with it being a public setting but I’m sure you do that all the time at home? There’s no way you stay within arms reach of your baby the entire time they’re in the high chair every time, even if it’s to pop to the kitchen to grab something and come back? If baby was in direct line of sight of dad and the room was quiet with no people passing near the high chair (to risk knocking it over) or between baby & dad to affect visibility then I don’t see a problem.
If the high chair was a falling risk by itself then I don’t think being across the room would make much difference, it could fall while you’re sat right there eating.
I know as a mother it’s hard to imagine anyone else caring about our baby the same way we do, but from his reaction it sounds like you’re often criticising him when he’s alone with baby which can really grind down someone’s confidence as a parent.
But maybe I’m wrong on all my assumptions 🤷🏼‍♀️

He could have waited one minute for you to arrive, and not left baby alone.

You should never leave a baby alone in a highchair and especially in public bug I think you could have been a bit more gentle with him.

wtf how is she the AH he did what he did and then instead of taking accountability he gaslighted her! WOMEN ON THIS APP WTF IS GOING ON
