Super annoyed... I have my 20 week scan tomorrow and my husband and mother in law were coming with me. My husband texts me before going into work 3rd shift that his nephew is coming because his mother went to stay at her boyfriends. Now I have to be the bad guy because I don't think they allow children in the appointment and there's no way he's going to sit through the appointment and I don't feel ok with him in the room if they do anything internal. Leave it to my sister in law to put a damper on something that is supposed to be fun and exciting for me. And yes she did know my appointment is tomorrow and that my MIL was attending. 😡
