Would you let your 2.2 yo play upstairs, unsupervised but regularly checked, with your 6yo?

...just curious.

I would. Depends on the children concerned, though.

Of course!

Yes, I do - only get worried when it goes quiet!

MmeLindt, my kids always go for the earbuds too and i have at various times caught them walking round with them sticking out each ear! The thought of them falling over like that is just too much! (They do look funny though).

Mine are 2.9 and 6.9 and play on their own all the time, when i am on the laptop doing housework.

Yes I would/did

OOOOoooh, seemed to have ruffled a few feathers !
The OP asked for honest opinions - I gave it and so did meandjo. We can't all parent/live the same way or have the same opinions.
I don't wrap him in cotton wool and certainly am not one for following him around or being in the same room period, that would drive me insane!
Someone made a good point - it depends on your house. Although, she said "if it's a mansion". Well mine certainly isnt but it has high ceilings, therefore a large staircase so I would hear absolutely nothing and couldn't get there quickly and quite frankly, couldn't be arsed running up said staircase to check on them! Thats probably why the answers vary, the house will have a lot to do with it too.
I have one 2.4 yr old and one on the way. Unless we move to a house that has thinner walls then I wouldn't be leaving the 2 yr old upstairs.

Yes I would. I regularly allow my DD and her 4 year old playmate to play upstairs - in fact by the end of the afternoon I encourage it!

I know that theres nothing up there they can harm themselves with and close the stairgate and they shout to come down when they've had enough.

yes, mine are so loud i could always hear what they were up to... if a sudden silence decended i hastily checked and i had all bathroom doors closed... still have to do both those things and they're 3 & 4 now!

yes I do, DD is nearly 7 and sensible. DS2 is 2.5 and pretty good. I lock the bathroom and DS1's room but yes they play really well together up there.
No violence etc

yep with you bramshott and headfairy.

DH just changed living room door handle to one that dd1 (2.1) can open so she regularly runs off upstairs to play in her room.

Bathroom shut though.

I let mine play upstairs alone all the time. My dd (6) is more sensible than me and loves bossing her brothers around. It's not that I leave her in charge and give her responsibility she just takes it.

However, DSs will also play alone (2 & 4) but I check on them more regularly. My house is pretty childproof.

At what age is it seen as safe to leave them alone then?

whensmydayoff I think it is very different when you only have one child who is only 2.4yr.

I have two sons 6 and 3 and they play alone together upstairs. It is when it goes quiet I worry, we have a no shut door policy and my stairs open into my lounge so I can hear them.

As ds1 is 6 he is capable of judging situations to a certain degree, he can dress himself, go to the toilet, flush and wash his hands without the need to dispense kandoo everywhere. He can get his own drinks from the kitchen without the need to turn the tap of full blast and stick spoons under the water

He is also the biggest tell tale there is so when ds2 is doing something he shouldn't he is in a rush to tell me

Plus ds2 can also tell me when ds1 isn't sharing or playing fair. I think it helps when your child can talk fully and tell you everything the other one is up to.
