could you change your morning get uptime? I know with dd1 she would have 3+ hours in the middle of the night that were really unsettled so I normally didnt get out of bed until after 10 am (cant do it when you have other kids though ). She did get much better around three months. Day naps, or if you cant sleep lay down and close your eyes it helps. Slow cookers are great so you dont have to worry about getting dinner ready when baby is unsettled at night. I have expressd and lined DH up to do at least one feed tonight as he has only got up once to help since dd was born (he does do everything for the older girls weekend mornings though)

Might be worth talking to your DH and at least having 1 night on the weekend where he helps, even if you bf overnight he can get up get bubs, change nappies, burp and settle while you go back to sleep

its hard
