Baby shower guests

My friend told me she is throwing me a baby shower so I just gave her 10 contacts. 10 of those I know who actually care. Do you guys think I should invite more? I keep reading people who invite so many and they end up not showing up. I worry if just 5 cancel, there will only be my mom, 2 friends, n sister. Should I invite more? Will those I didn't invite be insulted? I didn't invite everyone because some I just know from seeing and we ain't really close.
