I live away from family and my best mate (She also has a DD 3) very kindly offered to babysit my DD 3 to give my DH and me a break. ( We have had one day away in 3 years. MY BF has weekly nights / weekends off as all her and her hubbies family around) when I arrived BF was super excited as her MIL had called up wanting to spend the day with her GD and on being told that my DD was there offered to take them both. So my BF said yes! This wasn't discussed with me and I had only met the MIL once in passing. I just let it go as my DD was so excited to hang out with her buddy. AIBU to think my mates bloody cheeky! She self admittedly would rather chew her own head off then look after her own kids and it obviously hadn't even occurred to her that I may have a problem with it but still...?
