I cannot understand why it would take two people to feed one baby at night.
Decide whose turn it is, use the suggestions on here to make it extremely quick so little howling, and then the other person can get some sleep.
I don't get the 'well that's just what happens when you have a baby' school of thinking about sleep. Sleep deprivation is associated with accidents and makes depression/PND worse. The more sleep, the better most people can function- doesn't matter whether a SAHP or in work-place. So, it's sensible for everyone to get as much as possible within the limits of having a tiny baby to feed.
First time around, bf, but all shared a bed, husband continually woken for changes/other reasons, everyone utterly exhausted, husband's work started to suffer after 6 months. Everyone ill and tired, marriage began to suffer as all so snappy. Second baby, bf, he slept on sofa in week, didn't get up for changes, had decent sleep, was able to work properly, me and baby slept better in one bed together- on weekends, he did dream feed late and took younger child out all day one day so I could nap/get rests.
Once I got to 6 months, I was back at work and crashed the car through exhaustion, at which point I did sleep training! I simply couldn't survive in my job (which requires travel and writing/creative thinking) with that little sleep.
The idea that two people made a baby so two people should become inefficient, exhausted, snap at each other and have more accidents is just daft!
