I think as bad as it sounds no one will look after your baby as much as you. And it’s such a high bar to set. You know your baby inside out. But the way I see it is we had to figure it all out with a newborn. My newborn cried constantly and I struggled through as any first time mum. Then eventually it all clicked. So if your baby does cry a bit more with dad then it’s just like when you first started out. I’d say as above have some trial runs and try to give him hints and tips without sounding condescending. 😬 I’ve left my boy with his dad a few nights while I have dinner out. I leave a schedule of when I do stuff and tell him he can do as he needs but ‘this may help things run more smooth’. As for the comforting yes I second, my partner can’t do this at all and also would get frustrated/ bored. But he just does the fun high energy play and that’s not always great before bed.
Also… does your baby use a comforter? You could wear it down your bra a few days then start getting baby to sleep with it. My boy has a teddy I’ve started using and he will snuggle his face into it once I put him in the crib and fall asleep quite instantly.
I felt a similar way with my little one and his dad, but honestly it was absolutely fine. I'd built it up way too much in my head. It'll do him some good to take the reins. Can you do a couple of trial runs in the next few weeks before you go back ? X
