If you're friends with parents of your child's classmates and you have more than one child, do they tend to be more the parents of your oldest child or your youngest? Or is there another variable like number of kids? I've noticed since we had a second that I seem to have more in common with the parents of my first child than the first time parents of my second. Maybe because we were all first time parents together and had lots of kid-focused questions/discussions, but this time around my attitude is more "hey, whatever works..." What's been your experience? Is it a mix? Does it change with time?
