Im soo bummed didn't get to invite a group of my former coworkers to my baby shower thrown by my family due to not enough room to accommodate many guests at my mom's house. How would you throw an "informal" baby shower for the group, but you don't have another person helping you out plan? I'm gonna be 32 weeks soon and I was already exhausted from the family baby shower.
