I will definately leave Em with my mum and step-father. They know Em really well and I know that they will respect my parenting wishes and only live a few minutes away. My Dad and step-mum live 40 mins away and I'm not sure I'd be as comfortable leaving Em with them. As for the IL's - well I've met them once. I know that DP has known them his whole life but I haven't so I doubt very much that Em will be ever be having sleep overs there.

I think its definately a personal choice and about your own level of comfort as well as that of your child!
