Input: My husband has a brother and a sister.  His sister and I have never gotten along, let's call her Amanda.  His brother is a fantastic guy and a close friend, let's call him James.

Amanda is exceptionally entitled and often rude.  We have known each other for 20 years, and have managed a civil relationship.

My husband and I were the first to have a child.  While several people in my husbands family insisted that they be invited to the baby shower, no one bothered to throw one.  I ended up not having a baby shower at all, which was a bit of a downer.

So the following year when Amanda was expecting, I did not throw a baby shower either.  She had three kids total (the last one only a month ago) and no one threw any baby showers that I am aware of.  I am not sure what my MILs excuse was, but no one held a party for me and I dislike Amanda, so I decided not to take the trouble.  

Now James, in his late 30s, has finally found the love of his life, Carla.  We are over the moon happy for James as Carla is a lovely and outgoing lady.  They are expecting.  I want to throw a baby shower, and show Carla our love and support. 

But is this a slap in Amanda's face?  She is definitely a touchy bitch, and very much my MILs favorite, so give me the tough love reddit.

tl;dr Did not throw a baby shower for one crappy SIL, now want to throw one for a nice one. WIBTA?
