Shall I get help from husband??

LO is 8wk and he is a terrible sleeper, especially during the day. His nap is only 20-30 min and hard to be resettled. This makes me have no rest during the day and I feel exhausted in the evening. My husband is working hard. He needs to leave 6.30 am and go back home at 6.00pm. I don't know if I should ask him to handle the baby during the night. It is not easy either as Lo need to be fed around at 1-2am and he is fussy at 3, 4 and 5 am for a while. I am really struggle because I am worried if it may affect my husband work. Anyone could give some comments?? Thanks in advance.
