Age Confusion

I'm one day from turning 29 and find myself wondering where I fit in with my peers who have already started families and when I will start one.  (Side Note:  For the first time in years excited to turn one year older!!!)  At church I feel like we're one of the older couples that don't have any children.  This means I befriend people younger than me who have children.  It's kind of strange in a way.  As a teenager and even into my young twenties, I preferred older friends, older boyfriends and talking with "adults."  I felt more connected with older generations.  NOW, I'm older and the older generation is like 40 something to me, and that's okay...but I feel I have less in common with them now.  They're done having kids now, settled in their homes and running around getting their kids to and from everything.  When they were 30, they were in the same position I felt I was in at 22, thus the connection.  Now I'm almost 30. LOL! :)  On Facebook EVERYONE is announcing they're having a baby....it's like someone turned on a switch and the whole world is preggers!  LOL!
My other thought with all of this baby stuff is;  Will I be a good parent???  I am so far detached from my younger years (in fact try to forget them).....will I understand and connect with my children well enough?  Maybe this is one of those points in life where you shit or get off the pot.  Either have children, or don't.  I have ALWAYS wanted a family with an exception of the last year or so.  I've really been on the fence about it lately.  Everyone's kids seem to get on my nerves and the parents do too.  I understand you want your child to feel like they have space to be creative...but do me a favor and watch them...don't just leave them alone and let them get into mischief.  I know things are supposed to be different when it's YOUR child....
Anyhow....maybe this is the point in my life where I get set in one way or the other.  You know, the older you get without being married/having children, the more likely you are to be set in your ways and get past the point of wanting those things?
Ramblings. :)
