Husband left his friends who I don’t know alone in our house with our 6 month old

You are not being unreasonable Op. At all.

There's a reason why childcare is the most regulated and everyone who works with children has a police check.

I reckon those yelling YABU would be the first to yell at a mom who left her baby at a nursery knowing they didn't check their staff.

Your baby is totally dependant on you and DH for her care and safety. You should think twice, three times and then again before leaving her with anyone. There were alternative ways of managing and talking through these will help you both feel more confident.

Best way forward is to have a conversation and plan for next time. Then if an emergency happens DH will know how to manage and what works for you and keeps your baby safe.

Best wishes for you and your family.

She fell off her bike, she’s broken her arm and collar bone.

Yes. This.

I'm amazed that people would rather an 11 year old sit in pain and not get the help they need as quickly as possible because asking lifelong friends to watch a baby for an hour - and evidently capably - is so outlandish.

They are strangers to OP! Just like if OP left the baby with her friends, who her DH didn’t know - unacceptable

It was an urgent situation and he had to make a quick decision, whilst potentially being a bit stressed. He decided it was better to leave DD with his friends, where she could have her bottle, rather than potentially crying for it in the car. They are his friends, not random strangers. It seems like a reasonable decision made in a rush. It would equally have been reasonable for him to take DD with him. Your DD is fine, so I would let this one go.

I never mentioned OP’s friends?!?! It’s not acceptable to leave the baby with anybody’s friends, unless both parents know them very well

Omg I would feel completely the same. I would be so so upset and I would struggle to trust his judgement ever again to be honest. He should have got one of the friends to take his sister. I also would struggle with him not having told you - I would never feel comfortable leaving the baby with him again as I wouldn't have a clue who was actually looking after her/him! Sorry to be dramatic but I'm surprised at all the people on here who are like 'meh'!!

She was agreeing with your sentiments that it was madness to assume one person's experience is the only experience and just because one posters child reacted in one way didn't mean others would react the same.

Aah I see .

I’m agreeing with you. My daughter’s elbow was broken but not a bad break. A double break would have been obviously a bad injury and so painful. I was just reading other replies that said ‘why the assumption she’s in agony as my child broke a bone and was fine’ which is obviously really daft.

He's known them since he was a toddler. They are not strangers

I think you've missed the poster point spectacularly here.

Ex AE nurse ,children definitely feel pain ! I have quoted my own child’s experiences as well! OP and many posters don’t seem to be too fussed about the 11yr old
Just because your child wasn’t in pain( which I find pretty remarkable ,particularly elbow area )doesn’t mean that this is usual .

How is that the obvious thing?! If he’d done that it would he “weaponised incompetence” - and if you were in a friends house when such an emergency arose would you not offer to look after the bay for an hour rather than the mother being called to come home?

What if roles were reversed and a mum left a baby with a friend because there was an emergency and the dad didn’t know them. Would it be ok for him to lose his shit too?

I can actually appreciate both sides of this.
From your perspective your baby was left with strangers when there was an alternative solution (DH to take baby and ask friends to leave).
From his perspective these are people he has grown up with, knows them and has probably seen them interact with children previously and felt they were trustworthy and was happy to leave DD. Plus felt it wasn't the best for DD to be sat in a car seat for like an hour when she might of been due a feed (sounds like she would of).

The issue here is it's the first time DD has been left without one of you. And I do understand why that's upsetting, it feels like a big decision with your first baby in particular, you want to make these kind of decisions together when your both ready and happy and because of an unforeseen emergency your DH made a call that goes against what you'd have been comfortable with. But you feel the decision has been taken from you.
But your DH is capable and able to make decisions for your DD too, it's part of parenting and you will come across situations in future that you don't agree on or have a difference in opinion.
The important thing is this was an emergency, and they aren't strangers to DH, it sounds more like he'd see them as family given the time he's known them.

oP you have many firsts to look forward to, and your DH didn't do anything wrong, he made his own parenting decision because he was the parent in charge. But I do get why that feels uncomfortable for you and why you'd have expected a different solution.

I despair honestly. So only the people the OP is friends with are acceptable to leave their child with? He's know them decades since he was toddler and yet you're acting like he handed the baby to the Yodel delivery driver.
