Diamond Star DA40 XL - 1st Time with Passenger

After being checked out in the Diamond Star DA40 XL I wanted to take my family up with me. I couldn't get everyone on board at the same time so I took them up one at a time. This was the first flight with my youngest son Gavin. However after this flight the marine layer pushed in and I was only able to take up my oldest son, Jacob, for one loop around the pattern.
