10 night vacation without baby?

I’m planning a 10 night international vacation WITHOUT my baby at the end of June. He’ll be 11 months. It will be me and my best friend. Baby will stay at home with his dad. His daycare and routine will remain the same during this time, and my parents and sibling live pretty much around the corner so they’ll be able to help a lot. He’s still BF but takes a bottle and formula too. He’s been eating great too.

The only thing I’m worried about is night time. He’s an ok sleeper now, wakes up once to feed sometimes and a few other times when he needs his pacifier back in his mouth or just bc. I’m worried my husband won’t be able to comfort baby as well as I can and that baby will have some sort of huge sleep regression because I’m gone. I’m okay if this leads to weaning off nursing, as I want to quit that by that time anyways.

Any tips/ suggestions?
