while doing shopping the last 3 days for my baby shower, I've started to feel so guilty for all the money being spent. I've even tried to come up with other options for things to spend a little less but they say it's fine. just really feel bad !! I wanna get my mom, sister & mother in law a thank you gift but I don't know what to get. doesn't have to be big or expensive .. something meaningful. any ideas ??
