Gave birth about 12 hours ago - have not passed motion yet. How painful is it going to be? Had a natural tear which required stitches.

Congratulations! I had a first degree tear with minimal stitches. I also had the same concern as you and was very worried when it was time to poop. Fortunately, my fears were unfounded and poop was actually not painful. Peeing was a bit more painful because the urine touched the stitches. Some doctors prescribe stool softeners, but you can also eat more fibre to soften the stools before trying.
