I have a question then. Being that I'm from a family with 6 kids and I'm second to last would that make me a middle child?

You could be considered a middle child or the youngest. How much older are you then your younger sibling?

4 years older than my younger sibling and 2 minutes younger than my older sibling.

I'd say you could still be considered either one. You're oldest sibling is like 10 years older, right?

Actually more than 10 years older.
