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

Whatever.

My DCs were exclusively bfed at this stage so they would have had to come with.

We would have had to find a solution that worked for both children.

Also possible here - maybe not the DH's preferred route- but possible.

Absolutely, not rocket science is it.

Isn’t anyone thinking of the baby here? Just the fact that the father should have equal say. I’d say his judgement was wrong, not so much as not trusting his friends, but he should have considered that your dc could well have been very anxious being left with strangers having never been apart from her parents before. That was his mistake (and actually yours too as it’s not the thing you’re concerned about). It would have been very easy given the circumstances to take her with him and he should have done that.

As an aside though, why didn’t his mum get a taxi?

Maybe because it's really easy to forget how time consuming leaving the house can be...
It's not the most challenging point to decipher is it.
My dts are 15 and I'm.so used to just getting up and going that I think it would be a shock to the system to have to manage it with a baby.

If my sister called me and I could hear my niece screaming in pain in the background, and they’d been told the ambulance wouldn’t be there for another 90 mins….

oh and I had just started feeding a hungry 6 month old, who’d needed burping and a nappy feed AND fought and despised her car seat

yep, I’d look over at the couple of friends in front me who were visiting no doubt to meet my baby… and I’d make a judgement call. He knows them, and he made the judgement call.

He made a decision in an emergency about the child you share. He doesnt need your permission for that any more then you need his.

It was far quicker and easier to leave the baby with his friends and deal with getting a child with broken bones to a hospital.

He left the baby with several friends. Do you think they would have taken turns hurting her? A few people is safer than one person if its abuse you're worried about.

Taking the baby to a&e was an option and it would have been fine to do this. The grown adult who was looking after his own baby made the decision to leave the baby with his friends. He made a decision about what he felt was best in the situation. Nothing bad happened so what’s the problem?

This makes it even more mad that you’re upset w your DH.

Except its completely unnecessary and disruptive to do that to the baby, unless you really needed to do it. And he didnt need to do it because he arrnaged emergency childcare

Honestly at 6 months I would have left my baby with my sister (who also had kids similar ages) or possibly one of my NCT friends who had known my child from
birth and also knew how to safely care for a child of that age- no one else.

But I was still breastfeeding at that age so the baby would have had to come with me anyway, especially since there’s no guarantee of how long one might be at A&E for (sounds like the DH was lucky to get back when he did).

It was an emergency. Not ideal of course, but I wouldn't dwell. Sounds like they did your hubby a fav and he trusted them enough to leave your daughter with them. If you trust your husbands judgement, then surely ok?
Edited to add, sorry, he should've given you a quick call.

I think YABU, sounds like it was an emergency and he knows these people even if you don't

My friends waited 4 hours for an ambulance when their child broke their leg playing football so it might not have really been an option if they could find another solution. Likely a massive wait at the hospital as well so best to get there quickly.

Personally I would have been taken aback - we never left our kids at that age so I think I would have expected my DH to call me so I could head home. Then he'd say 'but Eric and James are here' or whatever and I'd say 'that's fine, tell them I'll be back in 20 minutes' and then he'd go deal with the emergency and I'd head home in a taxi.

My husband and I have equal trust in each other and equal rights - but we do run things past each other. In this scenario I think it's fair enough to run the plan past the other parent as it's an unusual situation.

Honestly I've not a clue. Sounds like he made a sensible decision and the OP still got to enjoy her afternoon. I genuinely can't see why this is such an issue.

They wouldn't. Its the same time and time again

Incredibly callous to the poor 11 year old, any moment longer than necessary waiting in agony.

I don’t see an issue.
The baby is 6 months, not 6 weeks (that would be different).
Your DH’s sister must’ve been in agony so he had to move fast.
Your baby is fine so no harm done.
Assume you trust your DH and by extension his friends (and if not, there’s a bigger issue here).

No issue here at all OP

But he does, the dad. The baby is his right? And the baby was fine when you got home?

If you reversed this - ie my wife left the baby with her friends for a couple of hours, because she had to rush another child to A&E - nobody would batter an eyelid tbh.

So what on earth is your issue?

YANBU Leaving a 6 month old with some friends is a big call. He could have called you to check what you think or taken DD with him.

There is a lot new parents learn about feeding, safe sleeping etc. You don't know these friends well. It was an emergency but checking in with you and having a one minute conversation would have led to an outcome you were both comfortable with.

And you'd have been waiting hours.

There wasnt though.

His baby had someone looking after them as did his sister. He was the lift.

No wrong doing at all

All these people thinking he should ring op to come home.. good grief.
