Do I include my sons GF in our family picture
So my husband and I want to do a family picture with our adult children. My daughter is married so we want her Husband in the picture. One of my sons is not married but he has a LTR with a woman and they have a baby together so she will also be in the picture. My question is my other Son just started dating a girl less than a month ago but they have moved in together. She seems nice but we don't know her very well and I am unsure if we should include her in our family picture or is it OK not to invite her?
