Ds is 3.5. A family friend who we know fairly well has just started to babysit. She's only 13 but has done two cpr (first aid courses) and a six month 'babysitting' course, whatever that is. She's a sensible girl.
I've hired her to start looking after ds a few hours a week. I thought for the first couple of months I'd stick around. Just so I can work in the garden more. (Ds is a fucking nightmare 'helping' with the weeding- i.e. pulling out seedlings and it would be a huge help to have someone do lego and play with him.)
I was telling a couple of friends last night and they were all pearl clutchy and 
saying how unsafe it would be and they wouldn't dream of it.
I'm not planning on just buggering off and leaving her with him, I'll be around outside. This is fine right?!
And what age do you think someone can be left with a (bouncy) 3.5 year old? Depends on both of them right? Would it be awful to leave her with him for a couple of hours in a couple of months when I'm sure she's competent?
