history:  I couldn't believe how big my friend's baby had gotten since the last time I had seen her! My friend's baby has grown so much since the last time I had seen her! It's crazy how quickly kiddos grow! Even in a few weeks time! Do you see your friend and her baby often?
current: It had been about 8 weeks - I don't get out her way often, even though we live 30 minutes away.
next: That is how life goes! Different schedules and demands -- I'm sure she's so thrilled when she *does* get to see you!
