I was the first of my friends by a long way. The crowd I hung with in high school was like the straight A students, we all went to college (including me), one of my best friends graduated law school a while ago, several of my friends got their Masters immediately, so that's the kind of crowd I hung with...I had a baby at 19 (got married at 18, 6 months after graduating, pregnant 10 months after that.) So I can relate to being the first.
I bet you they turn out to be more supportive than you're thinking though. Especially with only one, all my friends loved hanging out with my kids when I only had 1 or 2, it gets kinda busy now that I'm pregnant with my 5th
