Leaving your baby with nanny/sitter/daycare

Di

I’m a FTM to a 4 month old boy. My husband and I have full time jobs, so we have a full time nanny during the day to take care of our son. We’ve had her for 2 months and it was hard getting comfortable with leaving him with her (it still is). But she’s good with him and he seems to like her. She’s taking some time off and we are either getting a temp nanny or daycare for a few days and I’m freaking out. I’m not comfortable leaving him with anyone else and what’s worse is he is scared of strangers now and screams when someone new holds him. Ugh 😑 I have so much anxiety over this I’m not sure what to do
