Apologies in advance for any breaches of etiquette. I'm new to the forum.
I spent the weekend at my parents' place with our 6 mo son to give my husband a bit of space to get some projects done. When we got back, I was doing some stuff in the kitchen while my husband watched the baby, who has a cold and is extra fussy. I let my husband know he could interrupt me if he needed to and that I was happy to take the baby if the crying was getting too much.
When the baby couldn't be soothed, my husband started cursing at him and became tearful with frustration. I offered to step in but he declined. The baby went from fussing to crying at which point my husband shook him a bit (not a serious head-flopping-back-and-forth shake, more like the way you might shake someone's shoulders to 'snap them out' of something.) At that point I took the baby from him and he went upstairs.
My husband is going to have a difficult week at work so I'm considering just getting an AirBnB with the baby to give him some additional space. But I tend to be a pretty catastrophic thinker and don't want to make things worse by overreacting.
If any additional context helps, this is not the first time I've been scared by how my husband handles the baby and we've had a few conversations about it. He'll go long stretches where he'll seem okay, but then something happens and he'll have an extreme reaction out of the blue.
Again, just wondering if I'm overreacting and if staying someplace else for a few days will only make things worse. Thanks in advance for the advice.
