She must be related to my exhusbands girlfriend.
B/G:My daughter, age 25, lives with her dad, and her daughter spends weekdays with them, and Saturday afternoon and Sunday with me. Granddaughters dad is not in the picture at this time.
We were at a graduation party last weekend, and my granddaughter wanted to bring a stuffed giraffe outside. I told her no, as a stuffed animal is not an outside toy. Ex's GF brought granddaughter inside, and brought her out with the giraffe. Granddaughter wanted to go inside, and I said no, everyone is outside, you can stay outside too. Ex's GF says, I can bring her inside for a while. I said no, she does not need to go inside.
I asked my daughter if G/F undermines her like that, and she said she does. Looks like I am going to have to up the firm spine quotient when I have granddaughter and the ex and his g/f are around.
