Would you expect more help?

My partners normal sleep schedule is from 3am to 10am (uninterrupted) and a nap from 12:30ish-2:30pm.. from there he works 3:30pm-1am, 4 days a week. He only held our son for 30minutes during the time he was up this morning (because I asked) but it kind of bothered me. I don’t expect him to do much, but come on. I get that he needs sleep for work, but um, I need a break. I think the amount of sleep he gets is unfair when I’m woken up every 2 hours with the baby 😕 am I being unreasonable or would you expect more as well?
