I need to see the GP for both myself and my son this week so I have booked two appointments as that is the way they prefer it. If it were a few things for myself then I'd just book one but for DS I will book his own appointment. I have always felt bad asking to be checked out myself if I've booked an appointment for my son or vice versa. Though if I was only asking for a referral then having DS checked out I'd just keep the one appointment.
