Permission no but I don't see why it wouldn't be communicated. R they uncomfortable with this? (me personally I would be)
@DeJah Yes, he knows about it and is ok with it.
I’ve traveled with my daughter without her dad 6x and have never been asked to show anything for her
It’s only if there’s a custody battle/issue otherwise no
If you think he’ll put up a stink about it then 100% yes and in writing like at minimum a text message. If he won’t hold it against you and trusts you with the baby out of state for a vacation then that shouldn’t be a problem but best to get it in writing just to be safe, even a text saying hey I’m taking (baby’s name) to (state) for (x amount of time), are you ok with that? And his yes response is what would cover you against him holding it against you.
I've never had to have written permission to do anything w my kids (travel, doctors, etc) married or not. I'd think the only reason you would, would be if yall had a court agreement
