When I was pregnant, I was completely convinced of two things: I was going to need to make a lot of personal adjustments in order to be as good of a parent as I wanted to be, and my best friend was going to be the most amazing aunt to ever grace a child's life. As it happens, my best friend is my sister, so she was going to be my baby's actual aunt, too. Since there wasn't really any kicking her from the squad, I felt doubly lucky that she's essentially the best person who ever lived.
Here's what I've figured out about aunts-to-be, whether they're biological or chosen: how they treat you while you're pregnant is a pretty good indication of what their overall vibe is going to be in their relationship with your kid. A good rule to follow is that how someone behaves in one relationship is usually indicitive of some variation of how they behave in all relationships. (Seriously, I dare you to prove me wrong on that theory.)
This is good news, guys. After all, this person is your best friend for a reason. Hopefully, you're more or less down with who they are. You love and trust them and generally consider their presence in your life to be one of the things that makes your existence a positive one. How could you ever doubt that they'll be an equally wonderful part of your kid's life?
In case you needed to run it down in list form (like you don't already know), here are just a few of the ways you'll get confirmation during your pregnancy that your BFF is going to be the greatest aunt who's ever aunt-ed, and your unborn kid basically doesn't know how lucky they already are:
