Too much to ask?

This is our second child and I don't remember it being like this the first time (20 months old). My husband was helping me at night. My son is 6 weeks old and breastfed but we were giving him expressed milk at night after I BF him so I could get some sleep. We decided to stop and stockpile. This week is the first week and I've barely slept. Baby is going through a growth spurt and up every few minutes. I'm exhausted. I mentioned to my husband again and asked him to help and get up again at one feeding to help me (put him back to sleep..something). He thinks that's unreasonable because he works all day and then comes home and works on house renovations and helps with our toddler. I still get her up, dressed, and ready for daycare every morning. I give her a bath at night, dinner is always on the table. He thinks I can just sleep all day. Did I mentioned I'm also in my last semester of college which requires a practicum and I'm taking the baby with me 3 times a week for 4 hours a time? I also have to do housework because who is going to do laundry? Or dishes? I'm so aggravated. Am I being unreasonable with this ask? I feel defeated.
