My husband doesn't think taking care of an infant is work?

I am so frustrated right now. I was trying to express to my husband that I want to make sure we'll each be doing our share of the chores after the baby is born, because once she's here I'll be doing as much work caring for her while he's gone as he does at his job. At which he scoffed and said that taking care of a baby isn't work. I was shocked, and I tried to reword it to see if he meant like it isn't the same as going to put a job, but he flat out told me that he didn't think that staying home and taking care of a newborn infant was as much work as he did at his job, as in EFFORT. He told me he thinks that it will be easy to do. That it doesn't compare with the tasks he has to do at his job (he is a butcher). I tried a thousand ways to explain to him that it did require effort and was just as tasking as a job outside the house, but no matter what I said or how I worded it, he insists that it will be easy and that what I'll be doing at home by myself doesn't compare with him having a job. I am baffled that he genuinely believes this, and hurt and offended that he thinks what I'm about to take on will be an easy ride while he's out doing the actual hard stuff. I'm also worried that he has no idea what we're getting into because he genuinely thinks I'm overreacting and making this bigger than it is. I don't know what to do about this. I'm half venting and half asking where to go from here. Any advice?
