Leaving baby with family for the first time?

Briana
How old was your LO when you left them alone with family for the first time? Mine is two weeks old and I feel like I'm losing my sanity. Me and my fiancé want a date night but I'm worried about leaving my baby with family for the first time. Granted it would only be a few hours, but I'm a FTM so I'm just being cautious.
