Who should get the nap?

I have a two day wedding today and baby is going through a 9 month sleep regression. I was up with her 7-8 times last night. My husband is off and will help hold my stuff and second shoot. It starts at 5 and he just took a nap! I told him that I was tired and he hasn't held her all day. I'm frustrated and was just looking for a little relief before the day. She is crying now and he's sleeping

Update:

I put baby to sleep and napped

I mentioned it later. I need to communicate my needs more
