Spending the night alone

Sweden

How soon is too soon to leave your baby for a few nights? My hubby wants to do a little vacation for his birthday and leave the baby with my mom.. he’ll be 5 months at that time. I’m almost dreading it and not wanting to go because I don’t know how well I’d cope and if I’d even enjoy myself for those 5 days we’re gone. Just looking for some other mommy insight, I’m a FTM and this is all very new to me
