Not Really Sure How To Feel

I just found out my baby sister is pregnant again.

She told my mom this morning. She is due the end of December.

Her and Nick (I think that is his name) are getting married. Not sure when, not sure where.

Holy shit.

I am in such shock right now.

I know it doesn't make any difference on their decision but I don't know how to feel about it. The only thing I do know is that I hope she doesn't go completely bat shit psycho like the last time she was pregnant.
