With my son's pregnancy I usually went with DH, but I did have my Mom, MIL, SIL and my BIL (my sister's husband) attend with me to various appointments.
This pregnancy I've attended the majority of them alone. It's easier that way- then DH can stay home with DS. DH has attended 2 appointments, I had my BFF attend one (she LOVED hearing the heartbeat) and now my FIL has shown an interest in attending. I talked to my midwife last appointment about my FIL wanting to attend. I wanted to make sure we wouldn't be talking about anything too icky hahaha. I had no idea he'd want to attend an appointment with me so I never invited him before, but he mentioned it at the beginning of this pregnancy how he'd like to attend (if I'm comfortable with that). He'll be coming with me tomorrow and he's soooooo excited!! haha
Do you attend all your appointments alone? Do you invite others to go with you?
