husband issue

so lately my husband has been kinda slacking off with taking care of our son he's 1 month old. takes naps on days off while I'm taking care of him and during night he tries to help out but takes him forever to get up so I just change n feed him. I told him today to feed him he says he doesn't feel good and tired! I'm home all day during the week and he sees the weekend as a free pass or something. it makes me cringe sometimes when he does things his way cuz my son cries a lot with him, he tends to raise his voice and impatient so I take him away
