Is it a MN crime to leave your sleeping baby in the garden, if you can't see them ?

I was on my PN thread the other day. And one of my lovely ladies told me that :
"There is a general feeling on here that leaving them out in the garden where you can't see them is a BAD thing though"
So is this a MN crime then ?
Becasue if I return from the school run and ds2 has dropped off, I pop him in the garden with the back door open. And the upstairs window open. And so I can hear him, if he makes a minor murmur. And I wander round the house, kitchen , upstairs, putting washing away. And I can not see him.
And I beleive this is o.k.
If someone had the sole intention of stealing him they would have to deliberately jump over my 6 foot wooden fence. Now this is of course A RISK. But I have considered it.
My mil swears that letting babies sleep outside is good for them.
There is risk. And then there is 'risk'. Are we not all becoming a bit too risk scared ?

I used to put my little one in his buggy in the garden with a fly net over him incase of wasps and stings etc, but when i spotted a fox in broad daylight leaping my 7ft fence it changed my mind completely.
I am fairly lucky that my whole garden is surrounded by a high fence and was not at all worried about him asleep in MY OWN garden and neither should you be.
We would never do anything if it was for ifs, buts and maybes. Fresh air is much better than being indoors.
