There are cots which attach to the parent’s bed and special blouses which allow for easy breastfeeding without undressing.

The whole process is as simple as dragging the baby over, taking one breast out and bringing them near to it. The baby will take care of the rest.

Mothers do get sleep, including during the day together with the baby. There are solutions out there for many frequent or rare problems. A good midwife and experienced mothers in the family / circle of friends are priceless.

I mean I'm sure it's tough but it's not forever. Also co-sleeping helps. Never understood why people get up to feed babies.

Breastfeeding and sleep aren’t mutually exclusive.

They definitely are for some mothers. It is very difficult for many people to wake multiple times during the night and still get a good night's sleep.
