Are you more tired during the day or night with newborns?

So I'm trying to figure out when we should get help.

I'm always sleepy during the day but have more energy at night.

When my newborn arrives we'll have someone to help 5-6 nights a week from 10pm to 9am. I'm worried that I'll be up all night anyway and her help won't be useful because I'll still be tired during the day.

My partner is also more of a night person, so although he is home 24/7 to help out, he might be exhausted during the day as well.

Or maybe I'll be so busy during the day I'll actually be exhausted at night for a change?

So ladies, if you get sleep at night, are you still tired during the day? What if you don't get extra sleep at night? Or are you someone that is tired during nighttimes?
