Babyshower!

Hey so my friend is doing my baby shower and my first baby shower for my son only 4 people showed up and this time around I'm sooo scared to be having a baby shower when I feel no one is going to show up! Not to mention my friend is wanting me to pitch in $100 for decorations and food! I worrie I'm going to go all out for a baby shower and no one is going to show up! Have any other moms had any trouble with this?? What should I do??!
