Keep on persevering! You know this application process inside and out. Use that to your advantage! How did you prepare for previous interviews?
It is natural to be nervous. I worked in undergraduate admissions and sometimes I was even nervous interviewing prospective students. If anxiety is overtaking you, then be the super confident alter ego of yourself. You got this!
This is my first time. Hopes definitely not very high, so I am happily surprised about this. I think with experience, the GPA becomes slightly less important, as long as your overall gets over that 3.0 hump, which can be very difficult. Overall, I have 222 graded hours (according to CASPA). It's almost impossible to raise my GPA at this point....
My daughter was 2 when I started school and I had a second kid halfway through didactic. I wouldn't recommend having any additional children while in pa school as the last half of didactic was kind of a blur. It helped us to set clear expectations before I started. The brunt of the child care kind of fell on her but we were prepared for that and worked through it. Clinical year I was able to stagger my more intense rotations (surgery/ER/IM) between my rotations with a more normal schedule and that gave me a little more time with them. No matter what, though, there just isn't a lot of family time to carve out but if you're all in it together you can double down and push through. There will eventually be an end to it.
