Baby fell off the couch while husband was "watching" him

The baby rolled off the sofa. Your DH was distraught and spent the day cuddling your baby.
It's not the end of the world. These things happen. My DD fell off the sofa when she was a baby. She's 18 now and absolutely fine (although being first time parents we overreacted and took her to hospital). That was a hard wooden floor too.
My DH was watching her and I was a bit annoyed but never worried about leaving her alone with him again.
You are being massively unreasonable to think you can't leave the kids alone with him.

In that case it sounds as though he has learned.

Ive posted before about an incident when DS2 was 6 months and he rolled off a caravan sofa on to the playmat on a hard floor. We went to French A & E and DH was left in no doubt by the Dr what he should not have done. In our case there was some gaslighting going on where I had repeatedly asked him not to have him on the sofa when DH was tired and he’d given me grief over it saying it was fine. I was in the shower when I heard the thud. DH had nodded off. I’ve never been so panicked in all my life.

When both DC were in bed later I said my piece and he knew I meant business. Never again did he cross me on child safety.

Could have happened to anyone, I know from experience that I've had to remind partner of new skills little one has developed and can't be left or can't be distracted by tv while baby is somewhere, i think he genuinely didn't mean it giving his reaction. It's all a learning curve no matter how many bubbas you've had

It does happen. I understand why you're pissed off, but the best thing is to prevent it in the first place.

Once they're rolling, it's a good idea to do as much on the floor as possible. Not just changing, but make it the default that baby is on the floor unless being actively held on the sofa. Get a rug or mat if you haven't already.

How often do you remind him that it's your third and his first? If you bring him down too much he will stop listening. He needs to find his own way as a parent just as you did.

Mistakes happen, he will learn from it.

And why not? Mums are allowed to have a life outside of child duties!

In your experience….

You're not overly anxious for being upset about this. It was an avoidable injury that could have been much worse caused by negligence. Your upset and worried reaction is normal

Oh gosh this reminds me of my post from last year 'my ex DP burnt my baby'

It's not excusable just because it's his first baby I never let my only baby roll into a hard floor

He needs to promise not to use his phone or watch tv when watching the baby.

I wouldn't trust him with all three tbh can you send your older two to their dads?

Mistake happen the one and only time I fell asleep with ds on the bed he fell off he was about 6 months old at the time.
DD was about 5 months old and had never rolled but she rolled off the sofa.

So you cried and he cried I mean it all sounds a bit…highly strung…

Surely you don't go to hens abroad as an adult mother of 3 for gods sake? Ff's.
And no he can't be trusted with the baby.

We've all been there. Bed a nice height for the back, floor a safe hight for a wriggly baby. Most of us end up on the floor. We did with all of ours.

When you are both new to parenting you develop your instincts and risk assessment together and this can include near misses or even accidental role offs, falls, knocks etc and you are more forgiving because you are learning together. But when one is new and one experienced the dynamics are different. The experienced one has developed acute risk assessment, as parents do, whilst the newbie is still learning.
You have to give him a bit of slak to catch up. Leaving him in sole charge for a couple of days is just what's required. He made a mistake but has shown he takes learning from it serious.

You know, I’ve read posts on here where the H has had something like this happen and gone off in a total strop at their partner and defensively blamed them and sulked for days. So I think PP was spot on asking you about his reaction, because it wasn’t this at all, it was the opposite. He takes responsibility and that tells you what you need to know.

I think this happens to most parents at some point. My second DC fell off the bed at about 6mo, hitting and knocking over the bedside table on the way down. I sure learnt my lesson!

As long as he learns from his mistake then I'm sure he can look after your children. Observe him doing nappy changes on the floor from now on :)

I would go with your gut feeling. If you are worried about leaving them then don’t.

That happens to lots of Mums and Dads, not unusual or something to be unduly angry over. Give him a little grace please OP

@Lorddenning1 perhaps now is the time to teach your partner to change the baby on the floor instead of the sofa! changing mat or towel is all that is needed. much safer for all. this was the only time I ever wore holes in my jeans!

When my kids were young I had a "thing" about them falling off things. On the basis that they couldn't fall off of the floor, I always changed nappies on the mat on the floor. They weren't allowed on the bed or sofa unless someone was holding them. End result was they never fell off of anything as babies. But then they made up for that from toddlerhood!

He made a mistake and will now realised you really can't take your eye off a baby once they start rolling. I learned this pronto when my baby rolled off the bed, while I was changing him. We all make mistakes - and hopefully learn from them.
