Wow! It takes 2 to make a baby and should be 2 to raise a baby, it’s his baby as much as yours. you really need to tell him to man up
The sleep deprivation is so hard, even with a very hands-on partner! You need to sleep/get help. It’s impossible to be awake 24/7. If he isn’t willing to help, dont be afraid to ask your family or friends! Even if they just come over to cook/look after baby whilst you shower/power nap. Traditionally women raised babies with lots of family/community around. You are not meant to do it alone.
What an old fashioned idiot!!
