Dreading girls day out

No

So my best friends wedding shower/bachelorette are coming up and it’s gonna be an all-day thing. LO will be with daddy all day, but it will be the longest I’ve ever been away from her (probably 10-12 hours). I should be looking forward to a day out but I’m just worrying instead, even tho I know she and her daddy will benefit from bonding time. Anyone been through this?
