So, you've invited her over and to a concert.

Did you ever suggest meeting somewhere closer to her place? Would you ever go to her?

Babies and children make going to really late events tough.

You might feel like you're reaching new out, but honestly they aren't very considerate for a new mom. Did you ever ask if you could come hang out with her and the baby at her house? I did that this past summer. A friend of mine had her first baby, and when I travelled to the city (from quite far away and for various reasons) I told her to just let me know what time worked for her on the day of we had picked, and I said I'd come to her. So I did.
