MIL wants us to get an agency babysitter over a weekend away so we can all go to dinner one evening . No-one else seems to have a problem with this but me! DP thinks I am being unreasonable and that alot of people do this. We have never had someone i don't know look after DD before , She is 3 yrs old and has only been look after by family members or friends when needing a sitter . She also goes to nursery ( which i view as different ) who here has used an agency and do you have any issues with it?
