to have hidden the window keys from DH

[2point4kids]

He is very cross. I think I am right though.

DS1 is 2.10 and a bit of a climber/escape artist.
We have to keep shut and locked all windows on top 2 floors of the house to ensure he is safe.

We open our bedroom window at night when its hot, fair enough. But DH kept opening it when he got in from work and was getting changed. Then he started opening it in the mornings at the weekend when he was getting ready etc.
More often than not he was forgetting t shut and lock it again.

Last time he opened it one morning then forgot to close it. I went upstairs with both children and went into babies room to put him in bed. Went back into our room and DS1 was on windowsill. Window was open.

Since then I have insisted window is open ONLY when we are both in bed and no other times.
I have hidden the key and wont tell DH where it is.

He just got in from work and is fuming because he said he wanted the key to open the window while he gets changed. I said no as he will leave it open!
He wants to leave it open from now until when we go to bed to cool the room down.
DS1 sometimes gets back out of bed in the evenings (he is going through a phase) so I said no to opening the window.
I have said we will put fan on in there when we go up so it will cool room instantly later and then open window when we go to bed (and close first thing in morning).

He says I am treating him like a child. But if he cant be trusted to act responsibly (and our childs life is at stake here) then thats the way it has to be. He is pretty responsible in most other areas, but just cant seem to realise how important this is enough to buck up his ideas.

AIBU?

here you go

Mothercare do window catches which allow you to limit how far the window can be opened. They are fine for UPV frames - we have them on ours. A friend's 2 y.o. dd once fell out of her first floor bedroom window onto concrete. It was the first time she'd ever climbed out of her cot - never mind the window! Miraculously she was fine, but it is a real worry, so I can understand where you're coming from on this.

2point4 - not really, old victorian houses, some with nasty upvc windows like us and some not.
ah well, will just hope to find them in the summer clearout we have planned!

CAn you leave the window open but lock your bedroom door so your child can not get in there to go near the window?

Yes you are treating him like a child but only because he is acting like one! If he cant take responsibility then you've done what you have to do to keep your child safe!

I don't think YABU. If your DH can't realise he has to shut a window for your child's safety then he needs to be treated like a child. I am paranoid about open windows and my 3yr old climbs up onto window-sills despite being told how dangerous/naughty it is, so we have to leave the big windows locked. I'd rather be hot and safe........ How about a high up bolt on the outside of your bedroom door to stop your ds getting in?

YANBU - I have the same prob with 3yo ds. Will only have the upstairs windows open if he is out.

It is ridiculous to assume a 3 yo can't open doors/stairgates, remove them etc.

All it takes is for one minute lapse in concentration for them to run upstairs adn fall out. There is solid concrete at the bottom for him to land on as well.

Windows opening at bottom are great for fire escape but terrifying for small children.

TBH I've looked at window restrictor things, but if I can undo them then he has a pretty big chance of doing it to.

It is my one huge fear that ds will fall out the window and I have nightmares about it. I'm completely with the OP on this one
