Child playing alone in garden

[Bitchfeatures]

AIBU, 2.5yr old playing in the garden alone. I think he's too young, DP says he will be ok and I'm been overprotective.
The garden has a 6ft fence and a locked gate, can see less than half of the garden via kitchen window, can't see at all via living room window, the back doors open so can hear but not necessarily see.
DS wants to be in the garden allll day, I sit out/play with him but it's a pain not been able to get housework etc done on the days we are home.
Who's BU?

I can see 3/4 of my garden and would let my 2yo play out and nip upstairs for stuff etc. Id be checking in and out every 5 mins at least. Would have let DC1 as she was a different personality. No fear, constantly eating stuff she shouldn't.

You know your child.

Who cares what the neighbours think? Do your neighbours make all your decisions for you @AntheasAcquaintance?

Playing alone in your garden will do your child more good than harm if you've removed any hazards.
When my children were that young we didn't have a garden. I would have been thrilled to be able to let them out whilst I got on with stuff I needed to do.

Inside the house is the place most children have accidents and even get killed.
Probably best to see if doctors could extend life in the womb until they start school ffs!

I voted YANBU but I really think it depends on the garden. Mine us an old fashioned cottage garden, and we also have a climbing frame/swing. There are unfinished things like a pile of slabs which ds2 tries to climb. He also likes to dig plants up , and put random things on his mouth, so I don't really leave him unsupervised. A friend has a lovely large rectangle of a garden. Decking and grass. Shed. Very very child friendly, I'd let him play in that.

I think its fine as long as back garden is enclosed and you have back door open for them to get in and out! Both myself&OH played in back garden from about 2.... and there was even a small pond! It was only about the size of a kitchen sink though. My sister was about 1.5 as long as I was out too(3yrs older). Being outside is good for children!
I wouldn't allow them to do it in the front garden at that age though, but enclosed back garden, I don't see the problem.
