It's a bit of a tricky subject to raise with her because her mum has been trying to tell her that we just want her here to babysit DD. This is NOT true at all but I'm scared that if I start saying what will be expected that it will trigger alarm bells in her head and she will think her mum is right.

She's not a girly girl and not really interested in babies (don't blame her - I wasn't at her age either) so I'm not really sure whether she will actually want to spend time of her own accord with DD. I think this is one of the factors stopping her coming back to live with us, rather than an attraction.

I'm sure it will all work out but just interested in what stuff others delegate to teenagers when they're busy doing other stuff? I should also say that DP is a shift worker so isn't around for dinner one week out of two. DSD has lived with us for eight months last year so we get along fine but last time I left all the chore allocation/monitoring up to DP which I probably can't do this time.
